Question

Can someone help me please, What does it mean if a scatter plot has an r-value of -0.964?

Answer 1

As the x-variable increases in value, the corresponding y-value decreases.

Here's a little more to study:

•Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one's height increases so does the shoe size.
•Negative Correlation: as one variable increases, the other decreases. Time spent studying and time spent on video games are negatively correlated; as the your time studying increases, time spent on video games decreases.
•No Correlation: there is no apparent relationship between the variables. Video game scores and shoe size appear to have no correlation; as one increases, the other has no effect.

Answer 2

Your scatter plot will appear as something similar to the attached one.
