In statistics, a central tendency (or, more commonly, a measure of central tendency) is a central or typical value for a probability distribution.It may also be called a center or location of the distribution.Colloquially, measures of central tendency are often called averages.hat is, given a measure of statistical dispersion, one asks for a measure of central tendency that minimizes variation: such that variation from the center is minimal among all choices of center. In a quip, dispersion precedes location.
Other non-normal distributions of re-sponse data can similarly result in a mean score that is not ahelpful measure of the dataâs central tendency.Because of these observations, experts over the yearshave argued that the median should be used as the measureof central tendency for Likert scale data.
