Based on the data, it can be concluded that the Spree headband produces significantly different measures of temperature than the Gold Standard and that there is no correlation between the measurements obtained from each of the two devices. The p-value derived from the experimental data equaled 1.097E-21, which is much smaller than the comparative p-value of 0.05. This indicates that the measurements from each device are significantly different, meaning the Spree headband measurements were not accurate, assuming the Gold Standard measurements were. The calculated Pearson's correlation coefficient equaled 0.1928 for the temperature data, which can be rounded down to 0, showing no correlation between the Gold Standard measurements and the Spree measurements. Had the Spree obtained measurements similar to that of the Gold Standard, there would have been a positive correlation. Therefore, based off the data in this experiment, the Spree headband does not accurately measure the temperature of the user. | Based on the data, it can be concluded that the Spree headband produces significantly different measures of temperature than the Gold Standard and that there is no correlation between the measurements obtained from each of the two devices.

According to the heart rate results, there was no significant difference between the Spree heart rate monitor and the gold standard which was achieved through conventional means of recording one’s heart rate. The standard error was .9 within each other and the p-value (.49657) was small enough to have no statistical significance in theory. With this it can be concluded that the Spree is reliable, and the graph showed a positive correlation between the measurements obtained from the Gold standard and the Spree. | |||

According to the heart rate results, there was no significant difference between the Spree heart rate monitor and the gold standard which was achieved through conventional means of recording one’s heart rate. The standard error was .9 within each other and the p-value (.49657) was small enough to have no statistical significance in theory. With this it can be concluded that the Spree is reliable, and the graph showed a positive correlation between the measurements obtained from the Gold standard and the Spree. Design Flaws and Recommendations
Experimental Design of Own DeviceWe would create an experimental group with individuals that have mild to severe asthma. We would induce an asthma attack using a variety of triggers that the certain individual reacts to. Afterwards we would have them immediately use the (name). Afterwards we would then use a spirometer to measure lung capacity and airflow. We would then survey the individuals and ask how they felt about the product. |
