Question

Statistics Unit Test 12 of 156 of 15 Items Question: Which measure of variability—range or IQR—best describes the spread of the dataset?

For a statistics assignment, Shayna randomly surveyed students on how many hours per week they spend playing online games:

1.0 1.0 2.0 6.5 10.0 10.0 10.0 10.0 12.0 12.5 14.0 14.0 14.0 14.0 15.0 15.0 15.5 16.0 17.5 18.0

Range; the distribution is skewed, and there are outliers in the dataset.

The range would be a better measure of variability in this case because the dataset contains outliers, such as the values of 1.0 and 18.0, and the distribution is not symmetrical.
