BLOG 27 - Experiment Graph. That is, interpret your hypothesis by making use of data

Figure 1: This graph shows the difference in high and low frequency of the sounds, and the varying tempos, volumes, and pitches. 

In conclusion, our hypothesis states that "the increase and decrease of tempo, pitch, and volume will induce or reduce stress on the heart, causing the heart rate and blood pressure to rise and fall." The graph shows that the results for tempo and pitch were about correct, but volume did not have much of an effect on the subjects.

As of right now, things are going pretty smoothly with our experiment. We have gotten the results for everyone in our group, which is good. One thing that our group discovered is that this experiment is not as simple to run as we thought it would be because there are so many tests that it takes a long time to test one person. However, it is not something that is completely out of hand, and so far we have executed it quite smoothly. One example of things going well are the results of my heart rate and blood pressure. My starting heart rate was 64 bpm. That raised when the pitch was higher on all of the trials and lowered a bit when the pitch was softer.

Blog 25 - Hypothesis and Methods

Our hypothesis is that if one increases the beats per minute (BPM) then the pitch and volume of the recording will cause the heart to become stressed, leading to a rise in one's heart rate and blood pressure.

Methods: 
First, headphones will be placed on the subject. The first set of beeps will be very slow with a high pitch and volume. After listening to the first set, we will measure their heart rate and blood pressure with an arm pump. The subject will then rest for three minutes in order for their heart rate to go back to normal. The second set of beeps will be very slow again but with a low volume and pitch. Again we will measure, and record their data and the subject will rest again for three minutes. The third set of beeps is very slow with a high pitch and low volume. Afterwards we will measure, and record data and the subject will rest. The fourth set will have a very slow BPM and a low pitch and a high volume. We will continue to measure the data and the subject will continue to rest for three minutes. The fifth set we do will have a very fast BPM with a high pitch and volume. The sixth will have a fast BPM with a low pitch and low volume. The seventh set we test will have a fast BPM with a high pitch and low volume. The eighth set will have a fast BPM also but will have a low pitch and a high volume. After each test we will measure the data with the arm cuff, then we will record the data and the subject will rest for three minutes. After all of this, we will compare our data to see if our hypothesis proves to be correct.

Blog 24 - Experiment Brainstorm

One idea that our group brainstormed for an experiment was to test how removing a certain food group from one's diet might effect one's strength. We were thinking that if we did this, 3 sets of 2 members of the group would remove a certain thing from their diet, such as dairy, gluten, or sugar. We would do a series of strength tests at the beginning to get each members overall strength and then we would do a series of strength tests again after 1 week and again after 2 weeks. Our hypothesis would go something like this - the strength of each person would go up as long as the person maintained a stable diet.
