Strategies
Being able to create a boxplot is an advantage on this exercise because it helps to understand the structure of the plot to answer questions.
 * 1) The boxplot is created by using a dot, line, line, line, dot to mark the minimum value, the first quartile, the median, the third quartile, and the maximum.
 * 2) The questions asked are a measure of spread and the median. The measure of spread can be the IQR or the range.
 * 3) The median is always the second blank, the measure of spread is the first.
 * 4) IQR is found by Q3-Q1 and the range is found by subtracting Max-Min.
