Question

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-values?

A. As the x-values increase, the y-values tend to increase.
B. As the x-values increase, the y-values tend to decrease.
C. As the x-values decrease, the y-values tend to increase.
D. As the x-values decrease, the y-values tend to vary randomly.

Answer 1

B. As the x-values increase, the y- valuebtend to decrease.

Answer 2

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.
