Comparing Dotplots
A dotplot is a graphical display of the distribution of a quantitative variable. Each dot represents one individual. The numbers on the horizontal axis are the variable values. A dotplot shows all of a variable’s possible values and the frequency of each value. Create the dotplots of per capita CO2 emissions (in metric tons) to answer more questions.
STEP 1: Select the “Several Groups” tab at the top of the page.
