Calculate the mean deviation from the mean for the data 57, 64, 43, 67, 49, 59, 44, 47, 61, 59

Asked by Sakshi | 1 year ago |  73

##### Solution :-

We know that,

Where, |di| = |xi – x|

So, let ‘x’ be the mean of the given observation.

x =

$$\dfrac{ [57 + 64 + 43 + 67 + 49 + 59 + 44 + 47 + 61 + 59]}{10}$$

$$\dfrac{550}{10}$$

= 55

Number of observations, ‘n’ = 10

=$$\dfrac{1}{10}$$ × 74

= 7.4

The Mean Deviation is 7.4.
