CONCEPT:

Mean Deviation for ungrouped data:

For ‘n’ observation x1, x2………….. xn, the mean deviation about their mean  is given by:  where N is the number of observations

CALCULATION:

Given data of numbers are 46, 34, 22, 26, 14, 20, 16, and 44.

Mean 

∴ Mean deviation  

⇒ Mean deviation =  = 10.18
