In this lesson, we are going to be talking about dot plots, and histograms in Excel. First we are going to talk about going from data to dot plots. Remember before we always had to go from data to frequency tables and then to some visualization. Dot plots are nice because they can let you go straight from data directly to the visualization. We are going to talk about going from data to histograms. Histograms are going to be really helpful to us especially because a lot of times we are going to have variables that have many values. Finally, we are just going to talk a little bit about plotting frequencies versus relative frequency.
