The Mean, Median, and Mode represent the three measures of central tendency. Mean is the average of a given data set. It can be calculated by adding the numbers in a given data set and dividing by the number of observations of the data set. The median is the middle number in a given data set. The condition is that the given data set must be listed in either ascending or descending order. The mode is the value that has repeated the most often in a data set.
The Mean
Mean= Sum of all the data set/number of data set
The Median
If the total number of observations (n) is an odd number, then the formula is given below:
Median=((n+1)/2)th observation.
If the total number of the observations (n) is an even number, then the formula is given below:
Median=[(n/2)th observation+(n/2+1)th observation]/2

The mode is the most frequently occurring observation or value.
