Line graphs are used to represent the relation between two scale variables.Two common types of relations depicted in these graphs are:
A) the predicted value of a dependent variable for each value of an independent variable and the change in a variable over time.
B) linear relations and nonlinear relations.
C) the predicted value of a dependent variable for each value of an independent variable and the line of best fit.
D) time and change, as well as nonlinear relations.

Question

Quizplus · Accepted Answer

Line graphs are commonly used to represent the relationship between two scale variables, such as the predicted value of a dependent variable for each value of an independent variable (such as in a regression analysis) and the change in a variable over time. Linear and nonlinear relations may also be depicted in line graphs, but these are not the only types of relationships that can be shown. Therefore, options B, C, and D are all incomplete or incorrect.
