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, three lines, and another 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.
