Panic! At the lab

Ever have a day where nothing went right? We had a series of unfortunate events so we couldn’t actually do the research we wanted to do. It’s not a huge deal, but what was impressive was the amount of things that went wrong, each thing compounded and let us continue the study up until the point where we were about to start. Only then did we find out we had to stop. There was no danger and the issue was figured out after the fact, but it was an impressive feat of events.


Day 42: Conditional Probability

Conditional probability pdf plot

How does this not exist on the internet?! This is directly from my book, so it looks a little… well loved.

Up to now we’ve been dealing with single variable pdf and the corresponding CDF. We said that these probabilities relied on the fact that our variable of interest was independent. However, what if we knew some property that impacted our probability? Today we are talking conditional probability and that is the question we will be answering. It’s going to be a long, long post so plan accordingly.*
