Measures of variability, such as standard deviation, range, and variance, describe how scores are dispersed or spread out in a distribution. Measures of central tendency, such as mean, median, and mode, describe the typical or central score in a distribution. Measures of relationship, such as correlation coefficients, describe the strength and direction of the relationship between two variables. Tables and graphs are visual representations of data and can be used to display both central tendency and variability.
