Which of these r-values represents the weakest correlation?

a) 0.6

b) 0.5

c) 0.4

d) 0.3

The correct option is D.

Step-by-step explanation:

R-values represents the correlation between two variables. R-values lie from -1 to 1.

If r=-1 or closed to -1, then it represents strong negative correlation.

If r=0 or closed to 0, then it represents no correlation.

If r=1 or closed to 1, then it represents strong positive correlation.

From the given option it is clear that the number 0.3 is nearest to 0. Therefore  0.3 represents the weakest correlation and the correct option is D.
