In the last lesson we covered how to look at the data in Excel and we talked about how to go from data to frequency tables using our count if function. We are going to take another look at those same examples that we looked at before except now we are going to be talking about the features of these distributions. In particular, we are going to be looking at their shape. There are couple of shapes you should know after this. One is uniform distributions. Another one is going to be called unimodal. Yet another is called bimodal. Especially we are going to be looking at one called normal.
