Question

Quizplus · Accepted Answer

Standard deviation is the best choice as it provides a measure of the spread or variability of a set of data. It takes into account the distance of each data point from the mean, providing a more comprehensive understanding of the data than the mode, median, or frequency distribution. The standard error would not be an appropriate choice for this comparison, as it is a measure of the precision of the sample mean, rather than the variability of individual scores.
