Example
In this example, the COVAR function is used to determine how closely related the price of heating oil
(column A) is to the temperature that this hypothetical homeowner has set on the thermostat.
=COVAR(A2:A11, B2:B11) evaluates to approximately -1.6202, indicating a correlation (as prices rose,
the thermostat was lowered).
