Experimental Errors:Throughout the experiment there were some errors. One of the main errors was that the Spree band could have moved around while walking and this could have resulted in some inconsistencies. Another experimental error was time interval. Since all of the group members were keeping track of time, the results could have differed. One of the major errors was that because data was being put up by a colossal amount of groups, there were inconsistencies in the way people did the experiment, so some data had to be removed in order to have reliable results and analyses.

Conclusion: Based on the results, it is clear that the Spree fitness band has multiple design flaws. One of the major design flaws was the temperature measurements. Instead of taking an exact temperature, the Spree gave a level for a range of temperatures. In comparison to the gold standard, the temperature measurements were clearly skewed because the band was on the subjects forehead and that is the temperature it took; the thermometer that takes temperature from the mouth. For their next Spree band, the company should make a band which measures exact temperature and also a more reliable way of measuring the temperature of the body's core rather then just the forehead.The way they measure temperature is qualitative and for more accuracy it should be quantitative. The temperature measurements could be improved by having an additional piece that could be placed in the mouth during exercise, but this could prove to be a bit cumbersome. In addition to the flaws associated with the temperature measurements, the design of the band is flawed. The material does not absorb heat well and also leaves terrible tan lines. A solution to this problem could be finding a material that is heat absorbent. One of the more reliable, but still not as accurate as the gold standard, aspects of the Spree band was its measurements of heart rate. In conclusion, the Spree band is not as accurate as the gold standard but it is sufficient.
