A stem and leaf plot displays numerical data by splitting each data point into a "leaf" (usually the last digit) and a "stem" (the leading digit or digits).

A histogram displays numerical data by grouping data into "bins" of equal width. Each bin is plotted as a bar whose height corresponds to how many data points are in that bin.

Dot plots and frequency tables are tools for displaying data in a more organized fashion. In this article, we review how to make dot plots and frequency tables.

Practice what you have learned about the crowding out effect and the impact of budget deficits on the real interest rate in this exercise.
