What does a low standard deviation indicate?

A low standard deviation indicates that the scores in a dataset cluster closely around the mean, which suggests that there is less variability among the values. This means that most of the data points fall near the average, implying that the values are relatively consistent and not spread out over a wide range.

In contrast, a high standard deviation would suggest that the scores are more dispersed and variable, indicating a greater spread around the mean. Therefore, understanding standard deviation is crucial for interpreting data distributions in various contexts, including appraisal and statistical analysis.
