In one of my earlier blogs, I used linear forecasting method to predict a team’s scores in the future. While that was darn close to reality (when we checked with actual results), it did not mathematically account for fluctuations or seasonality and the outcome was always linear. In this blog, I show another method (that […]

Quick! Pick a number between 1 and 10!
“Pick a number between 1 and 10”—There’s been plethora of variations of such a game manifested in ways of magic tricks, simulations, statistics, and for sheer intellectual and nerdy curiosity. But is there an answer? Better yet, is there a pattern? If so, what is it…and how can it be explained? Some experiments claim to […]
Simulating coin-toss in Excel
Most of us know that theoretically, there’s a 50-50 chance of getting a “head” from an unbiased coin-toss. There are numerous implementations and simulations done in virtually all programming languages around this age-old ‘riddle’. In this blog, I share a simple but very effective simulation in Excel. Here’s the simulation: As you can see, I’m […]
Cataloging system audio files and playing them back
In this blog, I demonstrate how to enumerate all the system audio files that comes with Windows, put the list in an Excel file. Then use that list to play each one with a click of a button. First, let’s look at generating the list of audio files in our system folder. They’re in windows\media […]
A basic spin-slot game in…Excel??
With Excel’s toolbox of thousands of formulas and VBA support, it’s not out of question to be able to create games although it’s not designed for that purpose. However, not for the sake of playing, rather for experimentation and learning, I decided to present a simple form of a spin game. Game Rules Have 2 […]
Phone number formatting tips (Excel and Python)
For most people working with data for a significant amount of time, formatting raw data from different sources are both a reality and a pain. Today, I show different ways to format an un-formatted string that contains phone numbers using Python, and Excel. Our task is to format it (either for human-reporting, or consumption by […]
Searching online (Google) with Python
In this blog, I demonstrate how to run a Google query from a Python app extremely easily. The harder part is just the set up and knowing what to install. So, let’s start with the set up details: You’ll need to install the following packages IN ORDER: 1) beautifulsoup4 2) google NOTE: The package to […]

This is part of a 3-part series on the topic. Please read the posts in the order for maximum clarity and context: 1. Sample Size and Margin of Errors. Everything you need to know and ++ 2. Sample Size (Contd.) 3. Sample Size in Python In this blog, we’ll use actual numbers to determine […]
Sample Size and Margin of Errors. Everything you need to know and ++
I’m not a statistician by profession or training. However, I find it fascinating with even the basics under my belt and find plethora of statistic’s practical usage. Without it, we’re really ignorant. With it, we’re equipped but not always best educated either. I heard the phrase again and again, “Correlation does not equal causation!” and […]
