My Data Table
My Data Table on _________________________________
Type of Exercise
For 1 Minute
Heart Rate (Beats per Minute)
(Number of beats in 30s x 2)
Trial 1
Trial 2
Mean
(average of 3 trials)
Trial 3
Sitting
(resting heart rate)
Walking
Running
How to calculate the Mean? The mean is the aver age of all thr ee tr ials.
If you were to continue to do more trials on average your pulse rate should be
close to the mean number. For example: If your mean for sitting was 90BPM
than if you did 3 more trials your BPM should be close to 90 for each trial.
Trial 1 + Trial 2 + Trial 3 = X Then take X divide by 3 = Mean
Do this for each type of exercise.
