  1. Week 4 recap: Total Probability Rule

    The probability lecture this week kind of hit a wall at one point in our Bayes Rule example. Here's a clearer explanation.

The first, and most straightforward, is descriptive statistics, that is, just describing what our data looks like---mean, median, correlation, that kind of stuff. The second is "inferential statistics," that is, use of statistics to make inferences about …
