-First calculate total x² which is 364
-Then, calculate mean of the observation which is 7
- then, divide x² by n( total no. of observations) > 364/6 = 60.666
- then, subtract square of mean which is 7²=49,from 60.666 > 11.666
Lastly do square root of 11.666 which is equal to 3.42
Now for coeff or V, divide SD by Mean
3.42/7 and multiply with 100
3.42/7×100 =48.85 is your answer
