In a scatter diagram, we describe the relationship between __________.
A) Two variables measured at the ordinal level
B) Two variables, one measured as an ordinal variable and the other as a ratio variable
C) Two variables measured at the interval or ratio level
D) A variable measure on the interval or ratio level and time

Question

Quizplus · Accepted Answer

A scatter diagram is used to show the relationship between two continuous variables measured at the interval or ratio level. The variables are plotted as points on the diagram and the pattern of the points can indicate whether there is a positive, negative or no relationship between them. The ordinal level (A) does not involve continuous data and cannot be used for scatter diagrams. Measuring one variable as ordinal and the other as ratio (B) is not recommended for scatter plots because it can lead to incorrect interpretations of the correlation between the variables. Time is not a variable that can be plotted on a scatter diagram (D).
