Solution
The most appropriate statistical measure to use when a teacher wants to know how close the scores of his students are from one another is C. Standard deviation. This is because the standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.
