The correlation coefficient measures the strength and direction of the linear relationship between two variables on a scatter plot. The value is always between +1 and -1, and is valued as follows:

-1 perfect downhill / negative relationship
-0.7 strong downhill / negative relationship
-0.5 moderate downhill / negative relationship
-0.3 weak downhill / negative relationship
0 no linear relationship
0.3 weak uphill / positive relationship
0.5 moderate uphill / positive relationship
0.7 strong uphill / positive relationship
​1 perfect uphill / positive relationship

From the choices, the weak correlation coefficients are:
C.) -0.103
D.) 0.204
