Which graph shows the strongest relationship between the two

Which graph shows the strongest relationship between the two variables? Which graph shows the weakest relationship between the two variables? In scrambled order, correlation values for these four graphs are -0.9, 0, +0.3, +0.6. Match these correlation values to the graphs. The following figure shows four graphs. Assume that all four graphs have the same numerical scales for the two axes.

Solution

a)

The correct option is (b) graph 2.

b)

The correct option is (c) graph 3

c)

Graph 1: +0.6

Graph 2: -0.9

Graph 3: 0

Graph 4: +0.6
