Associational indices for high measurement level variables:

Regression b

(asymmetric, 0 if variables are independent, shows direction, depends on SD)

Determinational coefficient (r2)

(symmetric, 0 if variables are independent, doesn’t show direction, doesn’t depend on SD)

Covariance

(symmetric, 0 if variables are independent, shows direction, depends on SD)

Pearson’s correlation

(symmetric, between -1 and +1;  0, in the cas of independency, doesn’t depend on SDs)
