A statistical way of measuring the variance of two random variables being seen or calculated in the same mean time duration. This measure is equivalent to the product of this deviations of matching values associated with the two factors from their respective means.

A statistical measure defined as provided two real-valued random factors X and Y, with anticipated values and .

The transformation of data kinds from wider to narrower in a few circumstances.

a statistical way of measuring the relationship of two variables, formed by multiplying the real difference of every adjustable from the mean, both factors being assessed as well, and averaging all these types of services and products.

(statistics) the mean worth of the product regarding the deviations of two variates from their particular means

A statistical way of measuring the difference of two random variables being observed or measured in identical mean-time duration. This measure is equivalent to the item associated with deviations of matching values of this two variables from their particular means.

A statistical measure understood to be provided two real-valued random factors X and Y, with anticipated values and .

The conversion of data types from wider to narrower using circumstances.

a statistical way of measuring the partnership of two factors, formed by multiplying the real difference of each and every variable from its mean, both factors being assessed at the same time, and averaging all such products.

(statistics) the mean value of this product of this deviations of two variates from their particular particular means
