[Video] Conversion Rates Meet Distributions

My brain hurt for a while when I started thinking about where “confidence intervals” came into play when looking at the results of A/B tests that were comparing conversion rates between two experiences. Eventually, things clicked for me, so I put together a video explaining both where the confusion lay and then how we can work our way out of that confusion.

For giggles, I built the entire presentation with R using the xaringan and xkcd packages so that the slides would be in the style of xkcd.com.
