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 10 3 30 11 12 132 12 18 216 13 12 156 14 3 42 --- --- --- 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
