I’m more familiar with the political compass quiz, so I took them back to back in order to compare accurately. Previously we looked at how you can use functions to simplify your code.Ideally you have a function that performs a single operation, and now you want to use it many times to do the same operation on lots of different data. The matrix must not contain NA values. SapplyValues is a political compass test that combines the questions of the Sapply test* with the UI of 9Axes, which is in turn based on 8values.
