Access answers to RD Sharma Solutions Class 11 Maths Chapter 32 Exercise 32.3- Important Question with Answers

1. Compute the mean deviation from the median of the following distribution:

Solution:

To find the mean deviation from the median, firstly let us calculate the median.

Median is the middle term of the X_i,

Here, the middle term is 25

So, Median = 25

\(MD = \frac{1}{n}\sum_{i=1}^{n}|d_{i}|\)

= 1/50 × 450

= 9

∴ The mean deviation is 9

2. Find the mean deviation from the mean for the following data:

i

Solution:

To find the mean deviation from the mean, firstly let us calculate the mean.

By using the formula,

= 17900/50

= 358

N = 50

\(MD = \frac{1}{n}\sum_{i=1}^{n}|d_{i}|\)

= 1/50 × 7896

= 157.92

∴ The mean deviation is 157.92

ii

Solution:

To find the mean deviation from the mean, firstly let us calculate the mean.

By using the formula,

= 13630/106

= 128.58

N = 106

\(MD = \frac{1}{n}\sum_{i=1}^{n}|d_{i}|\)

= 1/106 × 1272.6

= 12.005

∴ The mean deviation is 12.005
