Coefficient of Correlation (r)
measures strength of linear relationship between independent variable (x) and dependent variable (y)
Range of (r) is
from -1.0 to +1.0
\+1.0 = perfect positive correlation -1.0 = perfect negative correlation
(r) is Normally positive in accounting
Coefficient of Determination (R squared)
portion of total variation in the dependent variable (y) explained by the independent variable (x)
The Value of Coefficient of Determination (R squared)
is between zero and one
The greater the R squared
the greater the portion of total variation in y explained by x
