Question

The coefficient of mean deviation about mean for the first 9 natural numbers is

Answer 1

Answer:

First of all, we will find the arithmetic mean of first 9 natural numbers by adding all the observations and the sum is divided by the number of observations. Now, we will calculate deviation from mean for each observation then the absolute is calculated. Now to find the co efficient of deviation (about mean), we will calculate arithmetic mean of sum of absolute deviation and is divided by number of observations. The coefficient of mean deviation (about mean) for first 9 natural numbers is 0.44.
