## **Convert your intuition to evidence using Excel and Statistics**

In the world of product management and constant innovation, separating gut feelings from solid evidence is key to your success. This process is rooted in decision science, especially when it involves turning straightforward data into strategic decisions. It all begins with a hypothesis—a smart guess about how things might work. Before we dive deep into using statistics to test these hypotheses, let's first understand the basics. This is tailored for founders and product managers aiming to make more data-informed decisions in their roles.

## **What is a Product Hypothesis?**

A hypothesis in product development and product management is a **statement or assumption about the product, planned feature, market, or customer** (e.g., their needs, behavior, or expectations) **that you can put to the test, evaluate, and base your further decisions on**. It's crucial to note that a hypothesis arises from a position of limited knowledge and data, necessitating empirical testing to validate or refute your propositions.

Armed with a clear understanding of what constitutes a hypothesis, let's delve into the nuanced practice of hypothesis testing, where statistical rigor meets product creativity.

Armed with a clear understanding of what constitutes a hypothesis, let's delve into the nuanced practice of hypothesis testing, where statistical rigor meets product creativity.

### **The Core of Hypothesis Testing**

Hypothesis testing is a statistical method employed to ascertain the likelihood that a hypothesis regarding a product feature or user experience holds true. This process begins with the formulation of two hypotheses: the null hypothesis Ho and the alternative hypothesis H1

\- **Null Hypothesis Ho**: There is no effect or difference.

\- **Alternative Hypothesis H1**: There is a significant effect or difference.

### **Defining Success Metrics**

Success metrics quantitatively delineate the parameters of success, directly correlating to your hypothesis. For instance, the click-through rate (CTR) serves as a metric when testing the impact of button color changes.

### **Crafting and Conducting the Experiment**

Experimental design is pivotal, outlining the methodology for comparing variations and observing their impact. A/B testing is a common approach, where users are randomly assigned to experience different variations.

### **The Statistical Backbone: The Statistical tests and Beyond**

There are various statistical tests which are available for different use cases

1\. **T-Test:** Compare means between two groups.

2\. **Paired T-Test:** Compare means within the same group at different points.

3\. **ANOVA (Analysis of Variance):** Compare means among more than two groups.

4\. **Regression Analysis:** Examine the relationship between dependent and independent variables.

5\. **Correlation Analysis:** Measure the strength and direction of the linear relationship between two variables.

6\. **Cointegration Test:** Test if two time series are cointegrated, indicating a long-term relationship.

7\. **Stationarity Test:** Check if a time series is stationary.

8\. **Chi-Square Test:** Test the independence of categorical variables.

9\. **Jarque-Bera Test:** Test if a set of data follows a normal distribution.

10\. **Bootstrap Test:** Estimate the sampling distribution of a statistic through resampling.

```

## **Let's do a practical using our favourite tool "Excel"**

**Step 1: Define Your Hypothesis**

\- **Hypothesis**: Changing the "Contact Us" button color from green to blue will result in a higher click-through rate (CTR).

\- **Null Hypothesis**: Changing the "Contact Us" button color from green to blue will not result in a higher CTR.

This setup presumes that Variation B (blue button) is not inherently superior to Variation A (green button). The goal is to statistically prove whether Variation B enhances the CTR over Variation A.

**Step 2: Set Up Your Experiment**

\- Create two webpage versions: one with a green *"Contact Us"* button (Variation A) and another with a blue *"Contact Us"* button (Variation B).

\- Randomly divide website visitors into two groups to ensure unbiased exposure to each version.

\- Record the number of clicks on the *"Contact Us"* button for each group over a predetermined period, such as one week.

### Step 3: Get data

You can ask your data engineer or if you know a little about any tracking tool like GA4/ [Clarity](https://www.bing.com/webmasters/help/microsoft-clarity-55a30306)/ [Mixpanel](https://developer.mixpanel.com/reference/track-event) you can get this data from there if you've correctly configured the Tracker into your website/ tool

### Step 4:

After gathering data, we will perform t-test which is a powerful tool for evaluating the significance of differences between groups. The formula for the t-test is:

```

* **t** is the t-statistic.

* **x1 bar** is the mean of the first sample.

* **x2 bar** is the mean of the second sample.

* **s1** is the variance of the first sample.

* **s2** is the variance of the second sample.

* **n1** is the number of observations in the first sample.

* **n2** is the number of observations in the second sample.

## The Data:

The data provides information on the performance of two variations of the website's "Contact Us" button (green and blue) during a specified date or time period.

1. **Date**: Time of data collection.

2. **Visitor Count**: Total users on the website during that time.

3. **GreenBtn\_Clicks\_Visitors:** Clicks on the green "Contact Us" button, showing engagement.

4. **BlueBtn\_Clicks\_Visitors:** Clicks on the blue "Contact Us" button, indicating engagement with the altered design.

5. **CTR (Click Through Rate)** = (Visitors with Button clicks (Green/ Blue))/Visitor count \*100

```

Now we have to use excel's built in feature of data analysis for performing **"t-test for two sample assuming equal variance"** (check the below illustration)

```cv

```

The result will look something like this

{"layout":"hscroll","images":[{"src":"https://firebasestorage.googleapis.com/v0/b/maitake-project.appspot.com/o/pages%2FmCk4fivRH6XxNnQD3iA0I1Mcv9L2%2FFgjp2vuEwjr8vOyTN32I%2F1323da7b-099d-4cd4-be58-fb13af30b8ff.png?alt=media&token=601ded34-418c-4132-b170-62d60ccce4c0","id":"1323da7b-099d-4cd4-be58-fb13af30b8ff","width":744,"height":308,"filename":"1710129329832.png","type":"image/png","caption":"","border":false}]}
```

**In this P Value is 0.01455039 which is less than the significance level of 0.05**

Get the Excel sheet from here: <https://abhijit.objectstore.e2enetworks.net/hypothesis\_testing/website\_hypothesis\_testing.xls>

### Step-4: Identifying the insights

**How to read the results**

***The null hypothesis can be rejected, and it can be said that the change in button color had a statistically significant impact on the CTR if the p-value is less than the significance level (for example, 0.05). Thus, we cannot rule out the null hypothesis and conclude that the CTR was not significantly affected by the change in button color.***

This example shows that the test group's mean CTR is greater than the control group's (green button) and that the difference is statistically significant because the p-value from the T-Test is less than 0.05 with **95% Confidence Interval**. We can thus rule out the null hypothesis and conclude that the CTR was positively impacted by the **"Contact Us"** button's switch from green to blue.

So, the next time you find yourself scratching your head over a "unique" feature suggestion, you've got the perfect comeback: "Let’s see what the data says!" This approach transforms those "Hmm, are you sure?" moments into "Ah-ha! Let's test it" opportunities.

**Imagine this:** A stakeholder comes up with an idea that makes you wonder if they've been reading too much science fiction. Instead of a flat-out "No way," you can now say, "Interesting idea! Let's put it through our hypothesis testing process and see if the data backs it up." It's a win-win: you keep the peace, and who knows? Sometimes, the most out-there ideas turn out to be gold mines, as long as the data agrees.

## **Statistical Arbitrage: A Dive into Quantitative Finance Strategies**

Statistical arbitrage emerges as a powerhouse in the trading world, leveraging mathematical finesse and high-speed technology to tap into the subtle inefficiencies between financial instruments. It’s not just about buying low and selling high; it's an orchestral play of numbers, predictions, and precision. Here's how it unfolds in the labyrinth of the financial markets.

### **The Essence of Statistical Arbitrage**

At its core, statistical arbitrage is about playing the symphony of numbers across different instruments. This strategy is broadly split into two main approaches:

* **Directional Trading**: This straightforward method focuses on the movement of a single financial instrument. Simple yet risky, it's akin to betting all your chips on one number at the roulette table.

* **Pairs and Cointegration Trading**: Here lies the art of balancing. Traders pick pairs or triplets of assets whose values historically move in sync. It's like a dance between assets, where if one stumbles, the others are expected to follow.

### **The Science of Stationarity and Its Role in Trading**

Stationarity is the backbone of statistical arbitrage. For a process to be stationary, its mean, variance, and covariance need to remain constant over time. Unlike a random walk, which wanders aimlessly, stationary processes have predictable patterns, making them ideal candidates for trading strategies like mean reversion.

### **Tools of the Trade: Decoding Stationarity**

1. **Augmented Dickey Fuller Test (ADF)**: This statistical test is like a litmus test for predictability in financial data. It helps determine whether a price series is more likely to revert to a mean or continue on a wild, unpredictable path.

2. **Hurst Exponent**: This is your compass in the realm of financial time series. A Hurst exponent above 0.5 signals a trending market, while a value below 0.5 indicates a potential for mean reversion.

### **Crafting a Mean Reversion Strategy on Stationary Series**

When two assets have danced together historically, mean reversion strategy helps predict when they'll return to their synchronized steps after a misstep. Here’s how it works:

1. **Calculate the Hedge Ratio**: This involves using Ordinary Least Squares (OLS) to determine how much of one asset (say, stock A) you should hold against another (stock B) to balance their differing volatilities.

2. **Creating the Spread**: Using the first 90 days' data, traders create a 'spread' between the two assets, ensuring no look-ahead bias, a tricky but vital part of the strategy.

3. **Testing for Cointegration**: Finally, an ADF test on the spread helps confirm if the assets are indeed moving together over the long term, justifying the use of mean reversion.

### **Putting Theory into Practice: A Step-by-Step Guide**

#### **Implementing the Hurst Exponent Test**

1. **Gather Data**: Collect the sequential data for analysis.

2. **Prepare and Preprocess**: Ensure your data is clean and formatted for time series analysis.

3. **Divide and Conquer**: Break the data into smaller series of varying lengths.

4. **Calculate and Plot**: Calculate the R/S statistic for each series and plot these on a log-log scale.

5. **Fit and Calculate**: Fit a line through the plot to estimate the Hurst Exponent.

6. **Analyze and Interpret**: A Hurst Exponent above 0.5 suggests persistence; below 0.5 suggests anti-persistence.

#### **Conducting an Augmented Dickey Fuller Test**

1. **Understand the Data's Nature**: Knowing whether your data is predictable (stationary) or not (non-stationary) is crucial.

2. **Set Up Hypotheses**: Null hypothesis assumes non-stationarity; the alternative suggests stationarity.

3. **Perform the Test**: Use the ADF statistic to challenge the null hypothesis.

4. **Decision Time**: Compare the statistic with critical values to decide the nature of your data.

5. **Interpret Results**: A rejection of the null hypothesis confirms stationarity, paving the way for predictive strategies.

Statistical arbitrage isn't just a strategy; it's a high-stakes game of precision and prediction. By understanding the nuances of stationarity, employing rigorous tests like the ADF and Hurst Exponent, and meticulously crafting trading strategies based on these insights, traders can harness the power of quantitative finance to not just participate in the market but to anticipate its moves. Remember, in the world of trading, being forearmed with data is being forewarned about opportunities.

```

### **Background**

ABC Apparel is an e-commerce company that specializes in selling clothing and accessories online. The company operates through its online platform and uses Salesforce as its primary CRM system to manage customer data and sales activities. I was hired as a data analyst to conduct a recency, frequency, monetary (RFM) analysis to segment ABC Apparel's customer base and gain insights into their purchase behaviors.

### **Objective**

The main objective of the project was to identify ABC Apparel's most valuable customers and improve the company's customer retention and acquisition strategies. By conducting an RFM analysis, I aimed to segment the customer base based on purchase behaviors and identify patterns and trends to gain insights into customer preferences and behavior.

### **Solution**

The RMF analysis was conducted in several phases, including the following:Categorization: The first step was to identify the e-commerce company's assets and categorize them based on their importance and impact on the business. The assets included the Salesforce CRM system, Einstein for AI-powered analytics, and Tableau for data visualization.Threat identification: The second step was to identify the potential cybersecurity threats that could affect the company's assets. The threats identified included data breaches, malware infections, phishing attacks, and insider threats.Risk assessment: The third step was to assess the risks associated with each threat identified in the previous step. The assessment considered the likelihood of the threat occurring, the impact it would have on the business, and the existing controls in place to mitigate the risk.Risk mitigation: Based on the results of the risk assessment, the fourth step was to develop a risk mitigation plan. This plan included recommendations for implementing additional controls to reduce the likelihood and impact of the identified risks.

### **Methodology**

To carry out the RFM analysis, I gathered customer information, purchase history, and order details from Salesforce and Einstein. I used Tableau as my data visualization tool to create interactive dashboards to visualize and analyze the data. Using the RFM model, I segmented ABC Apparel's customer base into four groups based on their purchase behaviors:

1. **High-Value Customers:** Customers who made purchases recently, frequently, and spent a significant amount of money on each order.

2. **Mid-Value Customers:** Customers who made purchases within the last six months, spent an average amount of money on each order, and made purchases at a moderate frequency.

3. **Low-Value Customers:** Customers who made purchases over six months ago, spent a small amount of money on each order, and made infrequent purchases.

4. **Lost Customers:** Customers who have not made any purchases in the last year.

### **Results**

1. The data lake and reporting architecture have enabled Boeing to streamline data access, improve data quality, and gain insights into the product development process. The benefits include:

Maximizing Revenue with RMF Analysis: A Salesforce and Einstein Case Study

**Problem Statement: A leading online retailer faces a sudden dip in profitability for a $999 product at the beginning of 2022, despite a consistent trend in 2021. Our analysis aims to uncover the reasons behind this decline.**

**Key data points include:**

1. Shopping Event (Binary): Indicates special sales events.

2. Ad Spend (Numeric): Investment in advertising campaigns.

3. Page Views (Numeric): Visits to the product detail page.

4. Unit Price (Numeric): Price, factoring in temporary discounts.

5. Sold Units (Numeric): Quantity of units sold.

6. Revenue (Numeric): Daily sales revenue.

7. Operational Cost (Numeric): Daily operational expenses.

8. Profit (Numeric): Daily net profit.

### **Review Data:**

* Shape: 455 rows and 9 columns

* Null Values: There is no null value in the dataset

* Columns : By unique values we came to know that there is one categorical column ie: Shopping Event? rest of the columns have continuous data

* Data Type : Date and shopping events are object and boolean data types which can not be fed to the learning algorithm so they are required to be transformed.

* head: date column needs to be divided into day, month and year.

### **Exploratory Data analytics**

**In exploratory data analytics we are expected to know reason behind the dip in 2022**

**To visualize the data against the date we have extracted the year and month from the date field and also changed the data type of the date column from object to datetime by using pandas to\_datetime method and extracted the year and month by using pandas DatetimeIndex method.**

#### **Profit Vs Date:**

By visualizing profit viruses date we can see if there is actually a dip in profit in 2022 and visualize the strength as well. We will be using the seaborn library to visualize the data.

* **Plot 1: Avg. 'Ad spend' is relatively the same for both the year but there is more in July 2022 which increases revenue for the same month of the same year.**

* **Plot 2: Avg. 'Page view' is very low in 2022 which might be the main culprit behind the decrease in profit.**

* **Plot 3: Surprisingly avg unit sold per indices per month is more in 2022 dispite low profit**

* **Plot 5: Operational cost is high is 2022**

* **Plot 6: unit price is very low in 2022**

#### **Correlation map**

1. **Pearson correlation defines that there is a strong relation between all the  variables, but we are interested to see an exclusive relationships so we can telly kendall tau and spearman correlation which can give the direction of the relationship as well.**

2. **By Concluding kendall tau and spearman correlation we noticed below relations 2.1 page views and profit have positive relation**

### **Causal Effect and Root Cause analysis using Dowhy**

Dowhy is an open source Python library that aims to spark causal thinking and analysis. DoWhy provides a principled four-step interface for causal inference that focuses on explicitly modeling causal assumptions and validating them as much as possible.

In Dowhy the first step is to provide a causal relationship to the dowhy model. We have to provide the causal relation by our own experience. We have to pack the relation in networksx object container and then pass it to the model. Let's look at the code snippet.

```cv

```

### **Conclusion**

**In this article, we have  compared root cause analysis and causal inference by classical approach, mathematical approach and by using Dowhy library. In the classical approach we have using exploratory data analytics, in the mathematical approach we computed causal effect and divergence/ root cause using mathematical formulas, then we used dowhy open source library to compute the same ie: causal effect and root cause.** 

**The classical and mathematical approach give better understanding of the data whereas in dowhy it is very convenient to find the result but in dowhy we are not able to understand the backend calculation. Dowhy is a bit more computational whereas the mathematical approach is simple and less computational**

### **Potential Solution**

The decline in page views led to a drop in sales, and the decline in unit pricing had a detrimental effect on revenue as well. Let's talk about some of the possible fixes that may be put into practice for increasing page views.

1. Optimize your website for organic search: Search is the top way both individuals and businesses research new products and services. This means it’s critical for you to make sure search engines find your website and bring it to the attention of the right people through search engine optimization (SEO). 

2. Invest in paid search

3. Engage in social channels

4. Work with influencers: Find social influencers and bloggers who have sizable audiences in your target demographic. Posts shared by influencers can help boost awareness and your SEO value if they feature your products in an authentic way. 

5. Write blogs or articles: Publishing original content, either on your own blog or on industry websites, can position you as a thought leader. 

6. Drive awareness with public relations (PR): There are plenty of ways to do PR on a budget, either on your own or with the help of a small agency or freelancer. Local publications and websites are always looking for interesting stories and contacting their editors with a pitch can lead to wonderful visibility that will attract high-potential website traffic. 

7. Use retargeting display ads: Retargeting can capture the attention of customers who visit your website but leave without making a purchase.

8. Make the most of email: Email is still the preferred method of communication for many buyers, and it can increase traffic from your existing audience. Emails that connect at different points in the customer journey can be automated with minimal effort, freeing you up for other important tasks. These include welcome emails that introduce new customers to your brand, abandoned cart emails to bring people back to complete a purchase, messages highlighting best-selling items, and more.

As we embark on 2024, the echoes of technological marvels from the past year still resonate. In the realm of voice computing, advancements like Meta Glasses and the Humane AI Pin have pushed the boundaries of what's possible. They whisper promises of a future where our voices seamlessly orchestrate our digital interactions.

But beneath this optimism lies a paradox. While these devices showcase the potential of voice, challenges remain in establishing it as a standalone category. Consider the saga of Amazon's Alexa, a household name that still incurred a staggering $10 billion loss. This begs the question: are we struggling with monetization, or is there a deeper flaw in isolating voice as a tech force?

## The Current Landscape: Beyond the Hype

Let's peel back the layers. Devices like Meta Glasses and the Humane AI Pin, equipped with generative AI, represent the pinnacle of voice capabilities. But challenges lurk in the shadows. Dependence on visual interfaces for setup, privacy concerns, accuracy issues, social discomfort, and limited multimodal integration exposes the limitations of a voice-only experience.

Market trends and user behaviors add another layer of complexity. Studies reveal a preference for a hybrid approach, where voice and visual interfaces work in tandem. Users instinctively switch back to traditional interfaces in certain scenarios, highlighting the need for holistic solutions.

## Navigating the Future: Voice as an Enhancer, Not a Replacement

As we gaze toward the horizon, let's approach voice computing with nuance. While Meta Glasses, Humane AI Pin, Apple's AirPods Pro+, Google's Pixel Lens, and Microsoft's HoloVoice showcase its potential, they also reveal its true nature: a powerful accessory, not a replacement for visual interfaces.

Designers and product managers, armed with this knowledge, can pioneer solutions that leverage voice's strengths while embracing its symbiotic relationship with visual interfaces. In doing so, we can create tech solutions that resonate with users and stand the test of time.

**What are your thoughts?** Are we on the brink of a voice-powered revolution, or is its true potential as an enhancer, not a replacement? Share your insights and aspirations for the tech landscape in the comments below!  #VoiceComputing2024 #TechInnovation #NewYearTech #FutureTechTrends

Just finished Tony Fadell's awesome book "Build," and wow, did it have me reminiscing about the legend - Steve Jobs! Here are 5 things that really stuck with me:

**1. Simplicity Rules:** Less is more, even for tech geniuses like Jobs. He taught me to ditch the fluff and focus on creating products that are easy to use and understand. No more user manuals the size of phone books!

**2. Obsess Over Details:** Turns out, Jobs wasn't just picky, he was a detail ninja! He showed me that the little things – that perfect click of a button, the smooth curve of a case – can make a HUGE difference. ✨

**3. Tell a Story with Your Product:** Forget boring specs, Jobs emphasized that products should have a narrative. They should inspire and solve real problems, not just list features. Think iPod shuffle – tiny tunes, big freedom! ‍♀️

**4. Believe in the Impossible:** Jobs was a master dreamer, convinced you could achieve anything if you set your mind to it. His unwavering belief in the iPod, even when everyone doubted, is a constant reminder to chase those crazy ideas.

**5. Be a Demanding Mentor:** Okay, Jobs wasn't everyone's cup of tea. But Fadell showed how his tough love pushed teams to excel, to go beyond "good enough" and create true game-changers.

These are just a few nuggets from "Build" that left me inspired. If you're building anything (not just tech!), check it out

Data as a Political Asset

I collaborated with companies like Cisco, Avit, and HPE. I specialized in crafting Machine Learning models for Business teams. A notable achievement includes developing the [P2B (Propensity to Buy) framework for Cisco using H2O.ai ↗](https://h2o.ai/blog/2014/predictive-modeling-at-scale/)  Another highlight was creating the Business Impact Score post-COVID. Leveraging government data, we identified sites affected by COVID-19, predicting sales impact for DNAC and Cisco Collab devices.
