Computation of Covariance

Ungrouped Data

         For a population consisting of paired ungrouped data points {X, Y}

where,

                   mx is the arithmetic mean of {X}

                   mY is the arithmetic mean of {Y}

                   N is the number of observations in each population.

For a paired sample {X,Y}

where,

	is the arithmetic mean of sample {X}
	is the arithmetic mean of sample {Y}
N is the number of observations in each sample.
