Arrange the given data in ascending order

34, 38, 42, 44, 46, 48, 54, 55, 63, 70

Median = 1/2  x (T+T1)=(46+48)/2

=47

Mean deviation = 1/n Σ|xi−Me|

1/10 Σn|xi−47|

34-47 = 13 likewise find out all 10 numbers

1/10 (13+9+5+3+1+1+7+8+6+23)

=1/10(86)

=8.6

2nd question

Find the mean: (3+4+5+6+7)/5 = 25/5 = 5

Now as we did before

Mean deviation = 1/n Σ|xi−barx|

1/10 Σn|xi−5|

3-5 = 2 likewise find out all 5 numbers

1/5 (2+1+0+1+2)

=6/5 = 1.2
