Normal Quantile Plots
Normal Quantile Plots On Calculator
In most stats classes, the only way you'll ever have to make a normal quantile graph is on your calculator. Doing them by hand is just silly! So this video explains how to do that, as well as a couple of common errors to avoid (hint: stat-fit rules!).
Interpreting Normal Quantile Plots
Once you've got yourself a normal quantile graph, the next thing you've got to do is interpret the darn thing! I would argue that the first thing to do is look at the histogram instead, but if you can't do that (like a no-calculator quiz), this video shows you what these plots mean, and the common patterns to look out for.
