ABSTRACT
Up to here, all tests we performed were on continuous data (lengths, weights, time etc.). However, there is a type of data that we have been ignoring so far: discrete variables. That is, the natural numbers we use for counting (0, 1, 2, 3 . . .). 1 When we use discrete values to count anything, we talk about frequencies. For instance, if you want to compare the number of eggs between multiple nests, or the number of patients surviving after a specific treatment, you can't use the tests we described so far. To deal with frequencies, we need a new approach. But don't worry, you already know the basics and, unsurprisingly, these tests are also based on finding out squares.
