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 2.0 2.0 7.5 10.0 10.0 10.0 10.0 11.5 17.0 17.0 18.0

IQR; the distribution is skewed; and there are outliers in the dataset
Range; the distribution is skewed, and there are outliers in the dataset
Range; the distribution is symmetrical, or close to it, and there arent any outliers in the dataset
IQR; the distribution is symmetrical, or close to it, and there aren't any outliers in the dataset.
