The yield of Jower per acre for 10 districts of a state
is as under.
District ABCDEF G H I J
Jower [22 [29/12 23 18 15 12/34/18/12,
calculate mean deviation from mean.
Answers
Answer:
15
Explanation:
it is the middle term
The Mean Deviation of the series is 6
Explanation:
Computing Mean of the series as:
Mean = Sum of series / Number of items of Jower
Mean = 22 + 29 + 12 + 23 + 18 + 15 + 12 + 34 + 18 + 12 / 10
Mean = 195 / 10
Mean = 19.5
District Jower (X) Deviation (dy)= |X − Mean| (± is ignored)
A 22 2.5
B 29 9.5
C 12 7.5
D 23 3.5
E 18 1.5
F 15 4.5
G 12 7.5
H 34 14.5
I 18 1.5
J 12 7.5
Sum of deviation (Σ dy) 60
The formula for computing the Mean deviation (MD) as:
Mean Deviation (MD) = Sum of deviation (Σ dy) / Number of items of Jower (N)
Mean deviation = 60 / 10
Mean deviation = 6
