Problem: Covariance {{10,11,12,13,14},{3,12,18,12,3}} [ Calculator, Method and examples ]

Solution:
Your problem `->` Covariance {{10,11,12,13,14},{3,12,18,12,3}}


`x``y``x*y`
10330
1112132
1218216
1312156
14342
---------
`sum x=60``sum y=48``sum xy=576`



Population Cov(x,y) :
Population `Cov(x,y) = (sum xy - (sum x * sum y)/n)/(n)`

`=(576 - (60 xx 48)/5)/5`

`=(576 - (2880)/5)/5`

`=(576 - 576)/5`

`=(0)/5`

`=0`
