Survey Raking

It's quite common for survey respondents not to be representative of the larger population from which they are drawn. But if you're a researcher, you need to study the larger population using data from your survey respondents, so what should you do? Reweighting the survey data, so that things like demographic distributions look similar between the survey and general populations, is a standard technique and in this episode we'll talk about survey raking, a way to calculate survey weights when there are several distributions of interest that need to be matched.
