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
