The purpose of this experiment was to find out if sleep affects your pulse rate. My hypothesis for this experiment was the people with less than six hours of sleep will have a higher pulse rate. I predicted that if sleep effects pulse rate then a person who has less than six hours of sleep will have a higher pulse rate. Both of which are supported in tables 1 and 2. The average pulse rate for people with less than six hours of sleep was 75. This is just slightly higher than the plus rate of people with eight or more hour of sleep with an average of 73.67.
