What is a graph used to determine whether there is a relationship between paired data?

A scatter plot is commonly used to determine whether there is a relationship between paired data. It displays individual data points on a two-dimensional axis, with one variable plotted along the x-axis and the other along the y-axis. By observing the pattern of the points, one can identify potential correlations, such as positive, negative, or no relationship between the variables. Additionally, a trend line can be added to summarize the overall direction of the data.
