A violin plot is a visual that traditionally combines a box plot and a kernel density plot. This is typically created in R, Python languages using MATPLOTLIB and other applications/modules. However, I show here how to get it done using only PowerBI. About Violin Plots Before I go into how to plot it, let’s understand […]

How many cats and dogs are there in your city? (method and cool charts)
In this seemingly simple couple of charts, I demonstrate a few nifty tricks that are fun and effective. First, we want to find out how many cats and dogs in a few selected cities (around me) and come with an educated estimate based on data. Then, we will use some cool, free add-in to create […]
Usages of OFFSET
OFFSET() is a nifty function that when used in conjunction with other formulas be very useful at times. Here are some examples of how it can be used to optimize some tasks. In one of my earlier blogs, I demonstrated a formula to transform a matrix of data into a single, continuous column of data. […]
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 […]
Compare and understand: Spread and Consistency
Imagine you have a product line with an average price of $20, and another product line where the average is $100. Which has more spread? Imagine you have 3 players whose bowling scores you have (which are all over the place by the way) and you want to know which player is more consistent? Or, […]

NFL 2019 regular season is done. What have we learned?
Now that the 2019 NFL regular season is in the books, we have complete data available about the teams’ performances. What can we glean from them? In this blog, I share some findings, answers, and the process of analytics behind discovery of the answers. I will focus on overall team performance data, not individual positions, […]
A Real Data Merge Challenge (Excel)
Instead of demonstrating what each of the thousands of functions does in Excel, it’s most helpful, I think to demonstrate how to solve real-life scenarios and the formulas that come in handy as secondary. Today, I present this. The Challenge: You are given 2 datasets of fruits and their prices. One set includes some items/fruits […]
Claim: Most 13th of the months fall on Fridays anyway (+Test)
Someone claimed recently that most 13th of the months fell on Fridays in recent years. This claim came upon the heels of my blog on how to find Friday-13ths for any year in Excel. So, obviously I had to check it out for myself if the claim is true. And I want to check it […]
Weather report in Excel
Below is a 10-day weather report for Seattle in Excel using external data connections. The following is the live embedded sheet (however, online Excel does NOT support external data connections in the browser…yet). To get the data to refresh, just save the file locally or click Open in Desktop App button along the top of […]
