The standard deviation specifically measures the average deviation of each score from the mean. The range is simply the difference between the highest and lowest scores and does not take into account all the scores in the distribution. The mode is the most frequent score and does not provide information about how spread out the scores are. The mean is the average score but does not describe the variability of the scores.
