A psychologist is preparing a visual display for a correlational study to show how the mean level of self-reported anxiety changes depending on whether participants fall into the 1st, 2nd, 3rd, or 4th quartile of social media usage. What specific type of graph should the psychologist use, and which variable should be plotted on the -axis?
Question: A psychologist is preparing a visual display for a correlational study to show how the mean level of self-reported anxiety changes depending on whether participants fall into the 1st, 2nd, 3rd, or 4th quartile of social media usage. What specific type of graph should the psychologist use, and which variable should be plotted on the -axis?
Sample answer: The psychologist should use a line graph. The variable representing the four quartiles of social media usage should be plotted on the -axis.
Key points:
- Selects a line graph as the correct visualization.
- Places the four quartiles of social media usage on the -axis.
- Demonstrates understanding of plotting variables organized into distinct values.
Rubric: The answer must identify a 'line graph' as the correct graph type and specify that the 'four quartiles' (or 'social media usage') goes on the -axis.

Match each graphical display used in psychological research with the data situation it is best suited to represent.
A psychologist is conducting a correlational study to investigate the relationship between 'Weekly Exercise Hours' and 'Resting Heart Rate.' Arrange the steps in the correct order to create a line graph that depicts this statistical relationship according to the standards for correlational research.
A researcher decides to use a line graph instead of a scatterplot to analyze a correlational relationship after organizing the predictor variable into four distinct quartiles. True or False: This is an appropriate choice because line graphs in correlational research are specifically designed to represent how the mean of a variable changes across a small number of distinct values on the -axis.
Match each term with its correct description according to the standards for using line graphs in correlational research.
A researcher studying the relationship between 'Social Media Use' and 'Self-Esteem' organizes the participants into four distinct quartiles based on their usage levels and displays the results in a line graph. Which statement best interprets how the data is being summarized in this visualization?
A researcher is evaluating the most effective visualization for a correlational study where the variable on the -axis has been organized into four quartiles. To best depict how the mean of the continuous variable changes across these specific categories, the researcher should conclude that a(n) _____ graph is the most appropriate choice.
A researcher is studying the relationship between daily caffeine intake and cognitive performance. Caffeine intake is measured continuously in milligrams. To construct a line graph for this correlational research, the researcher groups participants into three distinct categories (low, medium, and high intake) and plots these categories on the -axis. True or False: This is an appropriate way to depict the relationship using a line graph.
In a correlational study examining screen time and sleep duration, a researcher decides to organize the screen time variable into four quartiles. To effectively display how the mean sleep duration changes across these four quartiles, the researcher should use a _____ rather than a scatterplot.
Arrange the steps in the correct order to evaluate a continuous variable's data and construct a line graph that depicts its correlational relationship with another continuous variable.
