Consider the graphs presented in this chapter. Notice how they are constructed. Answer the questions about the graphs below.

a. For the graphs presented in Figure 1.3, what is presented on the x-axis (the horizontal axis)? What is presented on the y-axis (the vertical axis)? Which of these is the independent variable in the Drews et al. (2009) study and which is the dependent variable?

b. For the graphs presented in Figure 1.6, what do each of the dots in the graphs represent? How do these graphs differ in structure from the graph presented in Figure 1.5? Note the differences you see between these graphs.
