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 the headband, while at the same time they were recorded by the "gold standards": a thermometer as well as a pulse oximeter. After the results were recorded from all the devices and the Spree Bands were compared to the measurements taken from the gold standard devices, it was the decided that the Spree Band was not effective in the measurements, the device is flawed and provided inaccurate measurements, and is altogether unappealing to consumers.
When comparing the pulse ox heart rate measurements to those of the Spree Band, it is important to look at Pearson's R value.

They will use the device as they would with a cholesterol tester. The patients will be blindly tested and the results from the device will be compared to the results of other traditional MS detecting tests.

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

100 people will be tested using the device: 50 people who have been diagnosed with MS and 50 people who have tested negatively for MS. They will use the device as they would with a cholesterol tester. The patients will be blindly tested and the results from the device will be compared to the results of other traditional MS detecting tests.
