Mean

In statistics, the mean is one of the measures of central tendency, other than the mode and median. Mean is the average of the given set of values. It denotes the equal distribution of values for a given data set. The mean, median and mode are the three commonly used measures of central tendency.

To calculate the mean, we need to add the total values given in a datasheet and divide the sum by the total number of values.

Definition

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean = Sum of all the observations / Total number of observations

Example:

What is the mean of 2, 4, 6, 8 and 10 ?

Mean = Sum of all the observations / Total number of observations

Mean = ${\frac {2+4+6+8+10}{5}}=6$
