Mean is the arithmetic average of a file set. This is found by adding the numbers in a file collection and splitting by the variety of observations in the data set.

You are watching: Which one of the following is not a measure of central tendency?

The median is the middle number in a data set when the numbers are detailed in either ascfinishing or descfinishing order.

MODE is the worth of the observation which has the maximum frequency.

The Standard deviation is a meacertain of dispersion. It is the action or process of distributing point over a broad area (nothing around central location)
