This video starts with discussion around how to represent different bivariate data. That is, Categorical + Numerical variables = back to back stem plot or parallel box plot. Categorical + Categorical = Two-way frequency table or percentage segmented bar chart. Numerical + Numerical = Scatterplot. If you’d prefer to skip ahead to the part about the tables, fast forward to the 2:41 mark. At this point, I run through the basics of how two-way frequency tables work just in case you were absent that day or not paying attention at all. Once you know what you’re doing, two-way frequency tables are simple enough to manipulate and get good info from.
