T-Test Temperature

T-Test Heart Rate
Pearson's R Correlation

We used the T-test for the data because we only had two sets and could compare their information in this test. We also used Pearson's R Correlation to find the linear correlation between the two data sets.

Average Temperature Average Heart Rate


After calculating our standard error we can see that the values are low so not that much error occurred with our data. Based on our T-Test results for temperature which were less than .05 we can determine that the data is statistically significant. But the T-test for the heart rate was more than .05 so this data is not statistically significant.


The Spree Headband is a band that you wear on your forehead that has a wireless performance optimization device to monitor your physical changes such as heart rate, temperature, speed, and distance. This headband has Bluetooth that connects to an app on your phone that you can get from the app store for free. This product is commonly used to monitor your health and fitness when working out or engaging in physical activity.

The Spree headband had many design flaws such as: the band making the head sweaty and hot, the band being bulky and uncomfortable, the temperature being shown as a level not as an actual value, the Bluetooth disconnecting if you got too far from your phone, and the heart rate being inaccurate and constantly fluctuating. These flaw could be fixed by creating a smaller technology, maybe something that could be worn on the wrist instead of the forehead. The way the temperature and heart rate are measured should be changed as well by giving the actual number, not just a level. Lastly, the Bluetooth needs to be able to go a longer range so you don't have to have your phone on you at all times. The company has created a new product that puts the technology into a hat instead of a headband that could fix the bulk and comfort issue, but it cannot be determined for sure without trying that product as well.
