What would a scatterplot look like if there is a significant negative correlation between scores of a coin-rotation task and a finger-tapping task?

A significant negative correlation between scores of a coin-rotation task and a finger-tapping task indicates that as the score in one task increases, the score in the other task tends to decrease. In the context of a scatterplot, this relationship is visually represented by a cloud of points that slopes downward from left to right.

This downward slope shows that higher scores on the coin-rotation task align with lower scores on the finger-tapping task, showcasing the inverse relationship between the two variables. In practice, when you plot each participant's scores for both tasks, you would expect to see clusters of points trending downward, reflecting this negative association. The more pronounced the negative correlation, the steeper the downward slope of the cloud of points.

Other possible representations of the data, such as an upward slope or random scattering, would not accurately reflect the relationship described by a negative correlation. Additionally, a straight line would indicate a perfect correlation, which is not the scenario when only a significant correlation is mentioned.
