Central tendency is the trend of values clustered around the averages such as the mean, mode, and median values of data. The main objective of central tendency is to compute the center-leading value of observations. Central tendency determines the descriptive summary and provides quantitative information about a group of observations. It has the capability to represent a whole set of observations. Let's see each type of central tendency measure in detail in the coming sections.
Mean
The mean value is the arithmetic mean or average, which is computed by the sum of observations divided by the number of observations. It is sensitive to outliers and noise, with the result that whenever uncommon or unusual values are added to a group, its mean gets deviated from the typical central value. Assume x1, x2, . . . , x N is N observations. The formula for the mean of these values is shown here:
