Fidnthe coefficient of variation for the following frequency distribution.

$\begin{matrix} Clasees & 0 - 30 & 30 - 60 & 60 - 90 & 90 - 120 & 120 - 150 & 150 - 180 & 180 - 210 Frequency & 2 & 3 & 5 & 10 & 3 & 5 & 2 \end{matrix}$

The sum and sum of squared corresponding to length x (in cm) and weight y (in g) of 50 plant products are given below.
$\sum_{i = 1}^{50} x_{i} = 212, \sum_{i = 1}^{50} x_{i} = x_{i}^{2} = 902.8$ and $\sum_{i = 1}^{50} y_{i} = 261$ , and $\sum_{i = 1}^{50} y_{i}^{2} = 1457.6$

Which is more varying, the length or weight?
