LAB 3A WRITE-UP
Blood Pressure Monitor (Gold Standard)
Paired T-Test Value (temperature): 1.097*10^-21
According to the p-value from the T-tests, the data from the gold standard and from the Spree headband were not statistically different. However, the data from the gold standard and the spree headband were not correlated according to the Pearson's R-value because it was not close to 1 or -1 for both temperature and heart rate. This means the data from the Spree headband is not correlated to the data from the gold standard even though it measured the same activity.
Design Flaws/ Recommendations: Some design flaws in the device are the ability to measure temperature, and heart rate accurately. In order for the temperature to be measured more accurately the device should be closer to the person's core because it provides a better source of internal body temperature. Moving the device closer to the person's core also can help increase the accuracy of measuring heart rate because it will have more access to major blood vessels.

Target Population, Need, and Problem Understanding
Needs of Population
Engineering requirements: monitor using conductive surface with built-in microprocessors to detect heart rate
2. The device must be able to compile data into a database and differentiate what the individual's normal pulse is
"Engineering Requirements: data-compiling technology
3. The device must be able to detect when the pulse of an individual deviates from the normal
Engineering Requirements:monitor using conductive surface with built-in microprocessors to detect heart rate
4. The device must be able to detect when the deviation of pulse becomes dangerous and contact emergency help
Engineering requirements: cellular technology able to contact emergency help
5. The device must have GPS technology to aware emergency help of the individual's location
Engineering requirements: GPS detection technology in a small chip

Mean: 82.35 82.46
p-value from T-Test: 0.649303374
A paired T-Test was chosed because there were 2 sets of data to compare, each collected from the same person.
The Pearson's R-Value is close to 1, indicating the two data sets are correlated.
