Dear Analyst Episode 26: Data visualizations for infectious diseases/ideas during coronavirus (COVID-19)

Given the media attention placed on the coronavirus (COVID-19) in the media the last few weeks, I thought it was important to take a step back and look at the math behind infectious diseases and how diseases spread.

Dear Analyst Episode 25: Structuring data challenge (denormalize data) with Get and Transform

This episode is based on a video and Tweet posted by Mr. Excel (Bill Jelen).

Dear Analyst Episode 24: Finding and ranking percentiles

I discuss how to calculate percentiles in Excel or Google Sheets using the PERCENTILE function.

Excerpts from Range by David Epstein and financial modeling

Range: Why Generalists Triumph In A Specialized World by David Epstein came on my radar after listening to another podcast. Thought the premise was interesting in that people who “dabble” in various interests and hobbies end up excelling (no pun intended) in life and have a more rewarding career. I read a few excerpts that […]
