The sum and sum of squares corresponding to length x (in cm) and weigh

1.	The sum and sum of squares corresponding to length x (in cm) and weight y (in gm) of 50 plant products are given below : ∑50i=1xi=212,∑50i=1x2i=902.8,∑50i=1yi=261,∑50i=1y2i=1457.6 Which is more varying, the length or the weight ?
Answer» The sum and sum of squares corresponding to length $x$ (in cm) and weight $y$ (in gm) of 50 plant products are given below : $\sum_{i = 1}^{50} x_{i} = 212, \sum_{i = 1}^{50} x_{i}^{2} = 902.8, \sum_{i = 1}^{50} y_{i} = 261, \sum_{i = 1}^{50} y_{i}^{2} = 1457.6$ Which is more varying, the length or the weight ?

Answer»

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

$\sum_{i = 1}^{50} x_{i} = 212, \sum_{i = 1}^{50} x_{i}^{2} = 902.8, \sum_{i = 1}^{50} y_{i} = 261, \sum_{i = 1}^{50} y_{i}^{2} = 1457.6$

Which is more varying, the length or the weight ?
