Ch. 13- finding symmetric data #92
Description
Ex 5 asks students to find one numerical variable in some data set that is nearly normal and one that is skewed. Turns out that all the histograms students have made so far are weird because most are bimodal (penguins due to species, bdims due to sex) or skewed (stuff from chredlin). There are other nearly normal variables in those data sets, but students have to work a little harder to experiment with a bunch and find them.
The solution may, in fact, be to go back to Chapter 4 and show an example of nearly normal data (in contrast to the weird penguin data).
