When the standard deviation is very small, it means that the scores in the set are tightly clustered around the mean. This makes the mean a good representation of the typical score in the set. When the standard deviation is large, it means that the scores are more spread out and may not accurately reflect the typical score. The range, which is the difference between the highest and lowest scores, is not a good indicator of the typical score as it is heavily influenced by outliers.
