5. The sum and sum of squares corresponding to length (in cm) and weight (in gm) of 50 plant products are given below:
Which is more varying, the length or weight?
For length x,
Mean,
We know, Variance,
We know, Standard Deviation =
C.V.(x) =
For weight y,
Mean,
Mean,
We know, Variance,
We know, Standard Deviation =
C.V.(y) =
Since C.V.(y) > C.V.(x)
Therefore, weight is more varying.
