For the data, x 1 = 21, x 2 = 42, and so on. • The symbol Σ (“capital sigma”) denotes the summation function. For the data, Σx i = 21 + 42 +…+ 52 = 290. Measures of Central Location . Mean (arithmetic average) The three main measures that summarize the center of a distribution are the mean, median, and mode.

Measures of Central Tendency Mean, arithmetic mean (X or M): The sum of the scores in a distribution divided by the number of scores in the distri-bution. It is the most commonly used measure of central tendency. It is often reported with its companion statistic, the standard deviation, which shows how far things vary from the average.
