Question

The mean of a data is defined as______

Answer 1

Mean is defined as the average of the given numbers. Mean is the sum of all the given data values divided by the total number of data values given in the set.

It is given by:

Mean$=$ $\frac{\mathrm{sum}\mathrm{of}\mathrm{observations}}{\mathrm{total}\mathrm{no}\mathrm{of}\mathrm{observations}}$

Hence, mean of a data is defined as $\frac{\mathrm{sum}\mathrm{of}\mathrm{observations}}{\mathrm{total}\mathrm{no}\mathrm{of}\mathrm{observations}}$.
