Quizplus · Accepted Answer

Scatter diagram is the best choice for displaying the relationship between two interval variables. It shows the pattern of the relationship between the two variables by plotting their values on a two-dimensional graph. The horizontal axis represents one variable and the vertical axis represents the other variable. Each point on the graph represents a pair of values from the two variables. The pattern of the points on the graph shows whether there is a positive or negative relationship, a linear or non-linear relationship, or no relationship at all between the two variables.
