Discussion Before performing this experiment we hypothesised that breathing exercises would cause the heart to relax, causing a decrease in heart rate and blood pressure. In addition, we predicted that the systolic pressure would decrease and the diastolic pressure would stay similar to the control test. Due to all of the three t-tests exceeding .05 (0.64659, 0.380067, 0.184003) the null hypothesis was accepted. The data didn’t show a significant change from the basal readings to the treatment readings so we failed to reject the null hypothesis. The null hypothesis was accepted most likely because the data wasn’t consistent amongst all the participants. A better alternative explanation would be that, there were many distractions in the room and experimental errors causing the data to be skewed. The treatment data regarding the basal heart rate, systolic pressure, and diastolic pressure consisted of error, causing the sample size to be 24 instead of 25 for the reading. A similar event occurred again during Recovery Three for the basal heart rate, systolic pressure, and diastolic pressure, causing the same result, a smaller sample size by one. …show more content…

This could have resulted in weakened data as well because the second group wasn’t experiencing the video for the first time during their exercise. In addition, the room wasn’t completely silent, which could have caused the listener to lose focus from the man’s voice in the video at times. Lastly, during the period of the three recovery collections people were reacting differently. Some people stayed calm and quiet after the breathing exercise, where others began talking and moving. This could have made the heart rate and the blood pressure, mainly systolic, increase in the moving test subjects, ultimately weakening recovery
