On your spreadsheet, calculate your rest pulse rate per minute. Refer to Technical Hints to perform a product on a spreadsheet. Find the pulse rate per minute for each exercise duration. Refer to Technical Hints to perform a Fill Down function.
Create a line graph to compare your pulse rates under different conditions. Refer to Technical Hints to create a line graph.
Answer the following questions on paper:
How does your pulse rate change with the duration of exercise? Do you notice any other patterns or trends in the data?
Using the data you have collected to make a prediction about your pulse rate after 3 minutes of exercise and after 5 minutes of exercise. Write a few sentences to explain how you made your prediction. Try it out to test your predictions. How close was your prediction to the actual results? Do you notice any new trends now that you have more data?
Find another two teams and compare their pulse rates per minute for each condition. Add their results to your spreadsheet. Refer to Technical Hints to add data to spreadsheet. Make a line graph that includes all of the data from the three teams. Refer to Technical Hints to create a line graph from a larger data group. Write a paragraph comparing your group's data to the data from other groups.
Write a paragraph about what you learned from your results about your question. Cite evidence from your spreadsheet and chart to support your conclusion(s).
