when determining whether there is a correlation between two variables, one should use a

protractor
probability distribution
scatterplot
correlation coefficient

Explanation:

A scatterplot is a visual tool that plots pairs of data points for two variables on a coordinate plane, allowing observation of patterns or trends that indicate correlation. The other options are irrelevant: a protractor measures angles, a probability distribution describes likelihoods of values, and a correlation coefficient is a numerical measure (not visual).

Answer:

scatterplot
