Standard deviation is the best choice in this case as it measures the spread of a distribution and indicates how much the scores deviate from the mean. It provides a more accurate measure of variation compared to other measures like mode, median, or frequency distribution. The standard error is useful in determining the precision of a sample statistic, but not suitable for measuring variation in a population.
