The correct response is: The IQR is 1.5. This means that the shoe sizes for the middle half of the players are within 1.5 shoe sizes of each other.
Explanation: The IQR (Interquartile Range) is a measure of variability that describes the spread of the middle 50% of a dataset. In this case, the middle half of the dataset (from the 25th percentile to the 75th percentile) includes shoe sizes from 6.5 to 8.0, which have a range of 1.5. Therefore, the IQR is 1.5.
The shoe sizes for a varsity field hockey team are:
5.5, 5.5, 6.0, 6.5, 6.5, 7.0, 7.0, 7.5, 7.5, 7.5, 8.0, 8.0, 8.0, 8.5, 8.5, 9.0
Which of the following is the IQR and explains how this measure of variability describes how the values of a dataset vary with a single number?
