Question

Which graph shows data whose r-value is most likely closest to 1?

Answer 1

The first and third graphs are both negative, so we can rule them out. Also, the fourth graph has no correlation, so we can rule that out. That leaves us with the final and correct answer, graph B.

Hope this helps!

Answer 2

Answer:

Graph 2) is the correct answer.

Step-by-step explanation:

We know that:

r = -1 is strong negative correlation and 1 is strong positive correlation. 0 means no correlation.

Hence by the values of these r we can characterize our function.

Now in this question we are given that:

The graph shows data whose r-value is most likely closest to 1?

• As the graph 1) is a decrease in the values hence it shows a negative correlation i.e. r= -1. similar is the case for graph 3).

• Also the graph 4) is distorted i.e. it shows no correlation i.e. r=0.

Hence all the remaining three options are discarded.

Hence option 2) is true.

I.e. graph 2) represents  a strong positive correlation i.e. r-value is closest to 1.
