Measures of central tendency

The measure of central tendency tends to describe the average or mean value of datasets that is supposed to provide an optimal summarization of the entire set of measurements. This value is a number that is in some way central to the set. The most common measures for analyzing the distribution frequency of data are the mean, median, and mode.

Mean/average

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...
