PART II: PRACTICAL APPLICATION

Directions: Perform a statistical analysis of pulse rates.

Focus: Averages, medians, and modes

Background: The definitions of average, median, and mode are given in Section 7.1 of your textbook. In this activity, you will gather data on pulse rates and analyze the data by calculating the average, median, and mode.

1. First, locate your pulse. There are two places you can most easily find it. The first, called the radial pulse, is located on your wrist. Turn your palm up, and place the forefinger of your other hand on your wrist below the base of your thumb. The second pulse, called the carotid pulse, is on the side of your throat below the jaw bone under your ear. Again, use your forefinger to locate this pulse. Once you have found your pulse, decide which one is easier to find. Then use this location for the remainder of this activity.

2. Including yourself, ask 5 people to count his or her pulse rate under three different conditions - resting, exercise, and recovery. Rest for about 2 minutes, then find your pulse and count the number of beats in a 15 second period. Multiply this number by 4 to get your resting pulse rate in beats per minute. Record this number in the table below.

3. Next, measure your exercise pulse rate. Run in place for 1 minute, then immediately count your pulse for a 15 second period. Multiply this number by 4 to get your exercise pulse rate. Record this number in the appropriate column in the table on the next page.

4. Finally, measure your recovery pulse rate. Rest for about 3 minutes, and then measure your pulse rate as you did the previous two times. Record this number in the table as well.

5. Analyze your pulse rate data. Calculate the average, median, and mode for each of the three different pulse rates. Write your results in the appropriate spaces in the table above.

6. How do you think your results would differ if you found the pulse rates of more people? Which of the following would be effected the most, average, median or mode?
