Q. 3

# Calculate the mea

Given: set of first n natural numbers when n is an odd number

To find: the mean deviation about the mean

We know first n natural numbers are 1, 2, 3….., n. And given n is odd number.

So mean is, The deviations of numbers from the mean are as shown below, Or,  Or,  So the absolute values of deviation from the mean is The sum of absolute values of deviations from the mean, is   i.e., 2 times sum of terms, so it can be written as    Therefore, mean deviation about the mean is Hence the mean deviation about the mean of the set of first n natural numbers when n is an odd number is Rate this question :
