Recently, the Malaysian government has launched a campaign of 10 000 steps a day to create awareness to the public on healthy lifestyle. At the school level, all students are required to sit for the SEGAK test to determine the fitness level of students based on a few physical tests. Among the elements of the test is taking the pulse rate of each student. Based on the SEGAK test conducted in your school, get the pulse rate of 50 students before and after the step up board activity. Complete the table below by using the data obtained.

Students| Pulse rate(bpm – beats per min )| |
| Before| After|

Table 1
(a) (i) Find the mean, mode, and median of the pulse rate after the step board activity for the 50 students. (ii)Compare the pulse rate before the step up board activity of students in your school with a standard pulse rate. Give your comment. (b) Find the mean, mode, and median of the pulse rate after the step up board activity for the 50 students. (c) Construct a frequency distribution table for the pulse rate after the step up board activity using a suitable class interval. (i)Represent your data using three different statistical graphs based on your frequency table. (ii)Determine the mean, mode, and median of the pulse rate by using appropriate method. (d) Compare the mean, mode and median obtained in part (b) and (c). Give your comment. (e) Calculate the standard deviation based on the frequency table by using three different method. Draw your conclusion.

We know that physical activities are important for our health. But we must know the limit of the heart in older not to burden our organ. Resting heart rate between 60 to 100bpm can be regarded as normal to teenagers and adults. Heart rate depends on several factors including the level of fitness and environmental stress.
