Gold Standard - Average: 96.4974026 Spree - Average: 97.65584416 Gold Standard - Standard Deviation: 25.99859918 Spree - Standard Deviation: 27.10634861 Temperature Note: The "Gold Standard" temperature was measured with an oral thermometer. Gold Standard - Average: 95.48115152 Spree - Average: 93.79393939 Gold Standard - Standard Deviation: 10.76273631 Spree - Standard Deviation: 12.81217932 Inferential Stats Heart Rate P-Value (Paired): 0.298225789 Pearson's R: 0.730784539 Temperature P-Value (Paired): 9.25843E-05 Pearson's R: 0.797813158 Design Flaws and Recommendations When comparing the pulse ox heart rate measurements to those of the Spree Band, it is important to look at Pearson's R value. In this care, it is 0.730784539, meaning that there is a weak, positive correlation between the two devices. When comparing the P-Value (Paired) from the T-Test, 0.298225789, it is seen that it is greater than 0.05. This means that there is a significant difference between the measurements. When comparing the oral thermometer temperature measurements to those of the Spree Band, it is important to look at Pearson's R value. In this case, it is 0.797813158, meaning that there is a weak, positive correlation between the two devices. When comparing the P-Value (Paired) from the T-Test, 9.25843E-05 , it is seen that it is very close to zero. Based on the experimental results, it is determined that the Spree Band tracker is not effective for the intended purposes. The temperature and the heart rate were recorded from both the Spree (headband) and the Gold Standard Devices(an oral thermometer and a pulse oximeter). After the results of the Spree Band were recorded and compared to the Gold Standard measurements, it was determined that the Spree Band was not effective in its measurements. The device is flawed by providing inaccurate measurements, and is altogether unappealing to consumers. Experimental Design of Own Device
