Question

what would a perfect negative correlation look like on a scatterplot?
○ all points lie on a straight line that slopes upward from left to right.
○ all points lie on a straight line that slopes downward from left to right.
○ points are scattered randomly with no pattern.
○ all points are clustered at a single value.

Explanation:

A perfect negative correlation means as one variable increases, the other decreases in a perfectly linear fashion. This translates to all data points lying exactly on a straight line with a downward slope from left to right on a scatterplot. An upward-sloping line represents perfect positive correlation, random points mean no correlation, and clustered points represent no meaningful linear relationship between variables.

Answer:

All points lie on a straight line that slopes downward from left to right.
