In this topic we’re going to look at the basics of descriptive measures. I want you to know what they are, how to compute them (on your calculator and in a spreadsheet), and how they can be used to estimate a set of population parameters. And super importantly, I also want you to know how to come up with corresponding estimate of the uncertainty of the most common parameters using the so-called standard error. Most people can’t do the latter or they get confused in the process, so we’re going to dig deep and really make sense of it.
