Average Candidate Response
This is a graph showing the heart rates of two individuals during exercise. The heart rates of both patients are within normal limits during exercise. Mabel reached a higher heart rate than Albert during exercise with a peak heart rate of approximately 150.

Excellent candidate response
Excellent candidates will use the 'BlackStone Tutors Six Point Approach for Data Analysis'
This graph compares the heart rates of two individuals in response to exercise. On the X axis, time is plotted in minutes with pulse rate on the y-axis. The graph has data from two exercise participants: Albert, a 26 year old former athlete and Mabel a 36 year old office worker, with green and red line charts respectively. At the beginning of the test, the resting heart rates of both candidates were within the normal range, with Albert and Mabel’s heart rates of approximately 82 and 60 respectively. The heart rates of both candidates increase by approximately 10 beats per minute during what appears to be an initial ‘warm-up’ period. Albert’s heart rate increased smoothly during the main exercise period, whereas Mabel’s heart rate rose more abruptly with a steeper decline thereafter. Peak heart rates of 118 and 150 beats per minute were recorded for Albert and Mabel respectively. This can be explained by the facts that athletes have stronger hearts with a greater cardiac output; thus they require a lower heart rate to deliver the same volume of blood to cells, compared to non-athletic individuals. The higher resting heart rate is atypical, as athletes also generally have lower resting heart rates than non-athletes, however medication or co-morbidities may explain this variation. It would be beneficial to note the exercise performed as well as the time period entailed in better assessing the data.
