Variance is a measure of how spread out the data is from the mean. A high variance indicates that the scores are more spread out and different from each other, while a low variance indicates that the scores are more similar to each other. Therefore, variance is a good descriptive statistic for assessing how different or similar the scores are within a distribution.
