Question
The differences in the proportions of men and women in the three groups is best graphically portrayed by the ---Select--- pie charts or bar graph, since the unequal number of men and women tend to confuse the interpretation of the ---Select--- pie charts or bar graph. However, the ---Select--- pie charts or bar graph are useful in retaining the actual frequencies of occurrence in each group, which is lost in the ---Select--- bar graph or pie charts.

(These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 26? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here.arrow_forward
