IQR; the data distribution is symmetrical
The Interquartile Range (IQR) is typically used for describing the spread of a dataset when the distribution is symmetrical. In this case, since the data consists of a uniform distribution of goals scored, with an equal number of observations on either side of the median, the IQR would be the most appropriate measure of variability.
Number of goals scored in one season at Whitmore College soccer games follows:
0, 0, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4
