Which measure of association is unit-free?
A)=CORREL(Xdata,YData)
B)=COVAR.P(XData,YData)
C)=COVAR.S(Xdata,YData)

Question

Quizplus · Accepted Answer

CORREL(Xdata,YData) is unit-free because it only measures the strength and direction of the linear relationship between two variables, without taking into account their units of measurement. COVAR.P and COVAR.S both have units of measurement (e.g. square units) as they measure the variability of two variables together.
