I would like to use the Fitt's Law to test some hypotheses. It's the first time I use it, and I have some doubts.
Then, I would also like to test its validity in certain situations, as well.
In my experiment, I have two conditions, differing in terms of difficulty.
Intuitively, I think I have to calculate the predicted values, using the Fitt's formula and verify if they are correlated with raw data.
