mean deviation calculator

Let us learn about mean deviation calculator

The followings are the steps used in the mean deviation calculator.

Step 1: We use mean formula to find the arithmetic mean.

Sum of the given values
Mean = ----------------------------------------
Total number of values

Step 2: To find the deviation we use.

Deviation = mean – given values.

Step 3: finding the absolute deviation.

Step 4: finding the total of the absolute deviation.

Step 5: finding the mean deviation.

Sum of absolute deviation
= -----------------------------------------
Total number

Find the mean for the given problem.

24, 11, 40

Solution: Step 1: Mean (average) = 25

Step 2: Deviation = mean – given values = -1, -14, and 15

Step 3: absolute deviation (AB) = 1, 14, and 15

Step 4: Sum of the absolute deviation = 30

Step 5: mean deviation = 10

In our next blog we shall learn about mean and standard deviation I hope the above explanation was useful.Keep reading and leave your comments.
