Question 5 • Algebra: Concepts and Connections

Which graph shows data whose r -value is most likely closest to 0 ?

Answer
A
Image with description A graph shows both axes unnumbered. Points show an upward trend.
B
Image with description A graph shows both axes unnumbered. Points show a downward trend.
C
Image with description A graph shows both axes unnumbered. Points show a downward trend.
D
Image with description A graph shows both axes unnumbered. Points are scattered all over the graph.

Explanation

The r-value measures the strength and direction of a linear relationship. A graph with points scattered without a clear upward or downward trend has little linear association, so its r-value is most likely closest to 0. The other graphs show upward or downward trends, which indicate a stronger linear relationship.
