If mean deviation is 3.43 and coefficient
of mean deviation is 0.02, then
arithmetic mean is
OA) 171.5
B) 0.006
O C) 3.45
D) 0.0686​

Answer 1

Answer:

The coefficient of mean deviation is calcvilated by dividing mean deviation by the average. If deviations are taken from mean, we divide it by mean, if the deviations are taken from median, then it is divided by mode and if the “deviations are taken from median, then we divide mean deviation by median.

Step-by-step explanation:

For discrete series, the Mean Deviation can be calculated using the following formula.

...

Formula

1. N = Number of observations.
2. f = Different values of frequency f.
3. x = Different values of items.
4. Me = Median.
