Summary/DiscussionWhile performing the experiment with the spree band, many designs flaws were encountered. One of the design flaws that was encountered was not having a consistent method of recording time. While testing the temperature/heart rate of the subject, the stop watch that was used to record the time intervals had to be paused and resumed to ensure the accuracy of time. This experimental design flaw could be fixed by having an ongoing time, and recording the intervals of pausing and resuming. After comparing the results gathered from the experiment, it was concluded that the spree band data was not as accurate as the thermometer or pulse ox data gathered. By comparing the Pearson r coefficients and the data gathered from the T  tests, it was shown that the data gathered was not accurate when compared to the "gold standard" thermometer and pulse ox, which provided accurate readings. This may be due to the inaccuracy of the spree bands, or the fact that it is new technology and needs to be tested more.
LAB 3B WRITEUPTarget Population and NeedThe target population is athletes in training and people interested in fitness. This includes from ages 18 and up that have a stable weight to be able to calculate the percentage of sweat they are losing. This would be an affordable product for people of all income to be able to purchase it. The specific needs of the population is being able to detect early dehydration. By being able to detect early dehydration they are able to be properly hydrated and can optimize their workout. Device Design
