The sum and sum of squares corresponding to length x (in cm) and weight y (in gm) of 50 plant products are given below:

Which is more varying, the length or weight?
For length x:
Mean, ![]()
![]()
= ![]()
Standard deviation σ = √variance= √0.0784=0.28
![]()
For Weight Y
Mean, ![]()
Variance![]()
![]()
Standard deviation (![]()
![]()
Since C.V.y
C.V. x
⇒ weight is more varying.
