The best measure of variability to describe the spread of the dataset is the range, as it takes into account the highest and lowest values. In this case, the range of the dataset is 14 (99 - 85). The answer would be "Range; the distribution is symmetrical, or close to it, and there aren’t any outliers in the dataset."
