What is not a measure of dispersion in statistics?

Probability is not a measure of dispersion in statistics. Measures of dispersion are statistics that describe the spread or variability of a data set. They indicate how much the data points differ from one another and from the mean.

Standard deviation measures how spread out the numbers in a data set are around the mean, providing insight into the typical distance of each data point from the mean. The range calculates the difference between the maximum and minimum values in a data set, giving a basic measure of variability. Variance, on the other hand, represents the average of the squared differences from the mean, effectively capturing the overall dispersion of values within the dataset.

In contrast, probability refers to the likelihood of occurrence of particular outcomes and is not concerned with how much data varies. It is a separate concept from measures of dispersion, focusing instead on predicting events rather than analyzing their distribution.
