Considerations for Choosing a Measure of Central Tendency. 1  For a nominal variable, the mode is the only measure that can be used. 2  For ordinal variables, the mode and the median may be used.  For interval-ratio variables, the mode, median, and mean may all be calculated.
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.
