The mean, or average, is a number around which the observed continuous variables are distributed. This number estimates the value of the entire dataset. Mathematically, it is the result of the division of the sum of numbers by the number of integers in the dataset.

Let x be a set of integers:

x = (12,2,3,5,8,9,6,4,2)

Hence, the mean value of x can be calculated as follows:

Next, let's look at the median.
