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.
The interquartile range (IQR) is a measure of variability that describes how the values of a dataset are spread out. In this case, an IQR of 1.5 indicates that the middle 50% of the shoe sizes are within 1.5 shoe sizes of each other. This helps us understand the range of shoe sizes that are most common among the players on the varsity field hockey team.
