Explanation / Answer
Note : r = correlation coefficient .
If r = +.70 or higher Very strong positive relationship
+.40 to +.69 Strong positive relationship
+.30 to +.39 Moderate positive relationship
+.20 to +.29 weak positive relationship
+.01 to +.19 No or negligible relationship
-.01 to -.19 No or negligible relationship
-.20 to -.29 weak negative relationship
-.30 to -.39 Moderate negative relationship
-.40 to -.69 Strong negative relationship
-.70 or higher Very strong negative relationship.
a)
two variables in the above table have the STRONGEST correlation =
1 ) M1 and M3 which have correlation 0.683 , M2 and M7 which correlation as 0.610 ,
M2 and M1 correlation coefficient = -0.758 , M3 and M2 ==>> -0.536 , M5 and M2 ==>> -0.561
M6 and M3 = -0.645 , M7 and M3 = -0.489
2)Correlation coefficient value is greater than 0.40 .
3) Correlation coefficient value is positive since this is positive relationship .
Negative correlation with negtive sign .

b) two variables in the above table have the WEAKEST correlation
+.20 to +.29 weak positive relationship and -.20 to -.29 weak negative relationship
M5 and M3 = 0.265 , M7 and M4 = - 0.252 , M7 and M6 = -0.259
Correlation coefficient value is positive since this is positive relationship .
Negative correlation with negtive sign .
