C. Average distance between variable scores and the mean in a set of data

Explanation:

Standard deviation refers to the average distance between variable scores and the mean in a set of data.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation shows that the values tend to be close to the mean of the set, whereas a high standard deviation indicates that the values are scattered out over a wide range of scores.
