Question

question 1 of 10
which graph best represents the following situation?
as x increases, y increases; r = 0.42.
a. graph a
b. graph b
c. graph c
d. graph d

Explanation:

Step1: Analyze the sign of \(r\)

Since \(r = 0.42>0\), there is a positive linear relationship. So we can eliminate Graph A (negative relationship) and Graph D (no clear linear relationship).

Step2: Analyze the strength of the relationship

\(r = 0.42\) indicates a moderate - strength positive relationship. Graph C has a stronger positive relationship (points are more closely clustered around an imaginary line) compared to Graph B.

Answer:

B. Graph B
