Investigating Pulse Rate

• Electronic sensor can be used in a group
• Run more and repeat test to be accurate.
• There is a difference in arms.
• How the person is going to test the pulse.
• Not everyone grows the same, so the data set will not be accurate
• When the person runs, the rate increases then plateaus.
• Why it is important to test the right area of the body
