Question

Alya claims that the scatterplot shows a linear correlation. Enrique claims that the scatterplot has no correlation.

On a graph, points are grouped to form a horizontal cluster.

Which statement about their claims is true?
Alya is correct because the scatterplot clusters about a line with a slope of zero.
Alya is correct because as the x-values increase, the y-values remain the same.
Enrique is correct because the scatterplot clusters about a curve.
Enrique is correct because as the x-values increase, the change has no effect on the y-values.

Answer 1

Enrique is correct because as the x-values increase, the y-values do not change — a horizontal cluster shows no relationship between x and y (slope 0, correlation ≈ 0).
