## Analysis

When evaluating the temperature reading collected, the T value found was 1.25 * 10^-64 when comparing the gold standard to the spree.. Since this value was far below 0.05, it shows there is statistical difference which is not the desired outcome if we want the spree to function as accurately as the gold standard. Due to this statistical difference, it cannot be concluded that the spree is an accurate alternative to the gold standard. for measuring temperature. The Pearson’s R test value was 0.19624 which showed no relationship (correlation) between the Spree’s ability to measure temperature compared to the gold standard.

When evaluating the heart rate reading collected, the T value found was 0.098 when comparing the gold standard to the spree. Since this value is above 0.05, it shows there is no statistical difference which is the desired outcome if we want the spree to function as accurately as the gold standard. The Pearson’s R test value was 0.89 which showed a relationship (some correlation) between the Spree’s ability to measure heart rate compared to the gold standard but not a complete correlation since the value is not “1”.

## Summary/Discussion

After comparing the two devices, we concluded that the spree sensor was very inaccurate with measuring temperature however we found a stronger correlation with measuring heart rate between the gold standard and the spree sensor. Therefore we can conclude that the spree device is somewhat accurate in measuring heart rates of the test subjects and poor at measuring body temperature. The major flaw was the temperature gauge for the spree sensor was very inaccurate by only having four gauges. Between the four gauges, the gauge only changed once between being inside and outside. The gauge never reached level 3 or 4 in temperature even after working out. This showed that either the temperature gauge for 3 and 4 are either really high or very inaccurate in varying the temperature of the test subject. With heart rate, the two products were very close. We can conclude that the spree has a high validity for measuring heart rate, but not for measuring temperature.
