Galton proposed that measurement of human traits could be defined and summarized by two numbers, which are the mean and the standard deviation. The mean is the measure of central tendency that represents the average score of a group, while the standard deviation is a measure of variability that shows how much the individual scores tend to deviate from the mean. Together, they provide a summary of the distribution of individual scores in a group.
