Question

Quizplus · Accepted Answer

The difference between the highest and lowest scores in a distribution is called the range. The mean is the average of all the scores, the median is the middle score when the scores are ranked in order, and the standard deviation measures the variability or spread of the scores from the mean. None of these directly represent the difference between the highest and lowest scores.
