fill in the blank. when determining whether there is a correlation between two variables, one should use a to explore the data visually. when determining whether there is a correlation between two variables, one should use a to explore the data visually. scatterplot protractor correlation coefficient probability distribution

Explanation:

A scatterplot is a visual tool that plots pairs of numerical data points on a coordinate plane, allowing one to observe patterns or trends between two variables, which helps determine if there is a correlation. A protractor measures angles, a correlation coefficient is a numerical value (not visual), and a probability distribution describes likelihoods of outcomes—none of these are visual tools for exploring correlation between two variables.
