    This datafile, containing the area in square miles of each county in New Jersey, may be used to illustrate basic descriptive statistics. The file contains only 21 observations, so students may even calculate means, medians, etc. by hand if desired. A boxplot or dotplot is a good graphical summary of these data. A normal probability plot shows that county size has an approximately normal distribution.
