Answer:

Mean deviation is 2.4

Step-by-step explanation:

First let us make a data for the temperatures.

27, 25, 29, 30, 34, 24, 27, 27, 23, 24, 24, 27, 23, 27, 24, 30, 34, 25, 29, 27

We will arrange this in ascending order, so we have

23, 23, 24, 24, 24, 24, 25, 25, 27, 27, 27, 27, 27, 27, 29, 29, 30, 30, 34, 34

So range is given by = h - l (highest - lowest)

r = 34 - 23 or r = 11

To find mean deviation we need to find mean of the data.

So, mean = $\frac { (23+23+24+24+24+24+25+25+27+27+27+27+27+27+29+29+30+30+34+34) }{ 20 }$

= $\frac { 540 }{ 20 } =27$

Formula to use is ∑ $\frac { (IX-\mu I) }{ NI }$

Now we can write

Value Distance from 27

23 4

24 3

25 2

27 0

29 2

30 3

34 7

Mean deviation = $\frac { (4+4+3+3+3+3+2+2+0+0+0+0+0+0+2+2+3+3+7+7) }{ 20 } =\frac { 48 }{ 20 } =2.4$
