Document Summary

Central tendency is a statistical measure to determine a single score that defines the center of a distribution. The goal of central tendency is to find the single score that is most typical or most representative of the entire group. The mean for a distribution is the sum of the scores divided by the number of scores. If the scores in a distribution are listed in order from smallest to largest, the median is the midpoint of the list. In a frequency distribution, the mode is the score or category that has the greatest frequency. Use the mean for the most accurate measure of central tendency, unless: median: Discrete variables (because means are often fractions that can"t exist)
