The correct answer is: The IQR is 3.5. This means that the middle half of the players are within 3.5 shoe sizes of each other.
The IQR (Interquartile Range) is a measure of variability that describes how the values in a dataset vary around the middle 50% of the data. In this case, the IQR of 3.5 indicates that the shoe sizes for the middle half of the players (from the 25th percentile to the 75th percentile) are within 3.5 shoe sizes of each other. This provides a more robust understanding of variability compared to measures like the range, as it focuses on the variation within the middle portion of the data rather than the entire dataset.
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?
The IQR is 3.5. This means that the middle half of the players are within 3.5 shoe sizes of each other.
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 IQR is 1.5. This means that the shoe sizes for half of the players are within 1.5 shoe sizes of each other.
The IQR is 3.5. This means that the shoe sizes for half of the players are within 3.5 shoe sizes of each other.
