Before learning the central tendency formula, let us recall what is central tendency. A measure of central tendency describes a set of data by identifying the central position in the data set as a single value. We can think of it as a tendency of data to cluster around a middle value. Let us learn the central tendency formulas in the upcoming section.
What Is the Central Tendency Formula?
In statistics, the three most common measures of central tendencies are mean, median, and mode. Here are the central tendency formulas for each of them.
Formula to Calculate Mean
The mean formula of given observations can be expressed as,
Mean = Sum of Observations ÷ Total Number of Observations
Formula to Calculate Median
The Median Formula of a given set of numbers, say having 'n' observations, can be expressed as:
