Let's look at a new figure that contains the independent variables time and gender. To understand this figure, you must consider the effect of each separate variable and then look for combined effects of the two variables.

(Note: The data for this graph were created to illustrate graph-reading strategies. The graph is does not necessarily demonstrate the actual heart rate responses of men and women.)

As you consider this figure, try to answer these questions:

  • Quiz question 1:
  • How does low intensity exercise affect heart rate?
  • Quiz question 2:
  • How does gender affect heart rate?
  • Quiz question 3:
  • Does exercise affect the gender difference in heart rate?
  • Quiz question 4:
  • How do gender and exercise influence variability of heart rate?
