Rank the following sets of Correlation Coefficients based on strength of their relationship, starting from the weakest, and ending at the strongest? .75 -.04 -.42 .38 -.08 Solution For correlation coefficient : If it is from -1 to -0.07 then x and y have strong negative correlation. If it is from -0.07 to 0 then x and y have weak negative correlation. If It is 0 then x and y have no relation at all. If it is from 0 to 0.07 then x and y have weak positive correlation. If it is from 0.07 to 1 then x and y have strong positive correlation. Hence here from weakest to strongest : -0.04, -0.08, -0.42, 0.38, 0.75,......(as it is not mentioned about strong positive and negative).
