LAB 3A WRITE-UP
In this experiment the Spree headband was compared to other devices (gold standard) in reading both the heart rate and temperature of a subject. Based on the data collected, the Spree headband was much more accurate at measuring heart rate than measuring temperature. The t-test conducted for both sets of data found a p-value of 0.345106583 for heart rate and 8.79464E-10 for temperature. This shows that there was no significant difference in the data of the heart rate, but there was a significant difference in temperature. The inaccuracy of the Spree headband could be caused by the method used to find the temperature. Taking temperature externally is not very reliable; but there are instruments used by some doctors that take temperature readings from the forehead. Also, the fact that the Spree app does not give you an actual temperature, only a scale reading, does not help to improve the accuracy. Some possible remedies for this would be to give an actual temperature reading, and perhaps use more sensitive technology to get the readings, or move the Spree device so it is worn in an area that could give a better reading such as under the arm.

Target Population and Need
The target population for our device,TurnUp headphones, is mainly young athletes due to its unique specifications. It is able to measure heart rate and temperature but it also has settings that allow you to listen to your own heart beat as well as match songs to your heart rate. For example, if your working out and your heart rate is elevated, it will automatically play songs that have fast beats to get you pumped up. All of these setting can be controlled on your phone by using the TurnUp app.By using both the app and the headphones you can accurately measure, and record your workouts.
