Explanation / Answer
The histograms for Number of female friends is right skewed histogram becuase the tail is on right side. It is seen that the bins have one peak. Therefore, the data is said to be unimodal. The Zfnum plot is symmetric that means mean, mode and median is same. So, the make similar histograms for Number of female friends and Zfnum when the data set is said to be symmetric. But in reality, they are different. They may have change by changing the total number of females are equally distributed on the left and on the right of median value.
the histograms for Length of the friendship with their closet female friend is right skewed but it is more symmetric to number of female. Similary process is apply to make the histogram same is that mean, mode and median value having same value. This may changed by the total number of female and its friendship.
