Heart Rate (BPM) Gold Standard Spree Average 23.086987 98.940789 Standard Deviation 23.086987 24.837487 Count 290 291 Standard Error 0.0793367 1.4585075 Graph showcases the heart rate average of both devices with an error bar of standard deviation. Inferential Stats T-Test Graph for Temperature (Paired) Pearson's R:0.17295886 T-Test Graph for Heartrate (Paired) Pearson's R:0.66626956 A two-tailled paired t-test was deemed most fitting due to the nature of the data and study at hand, paired because each data point is matched to a unique data point of the second sample. The correlation coefficient was calculated as well to further examine the relationship between the two methods. With a p-value of 0.300 for heart rate measured by Gold Standard versus Spree Band, the difference between the two methods is not considered to be significant. This means that there is about a 0.3 probability of the two populations to be the same, in turn not allowing a significant difference to exist between them. The t-testing for the measurement of temperature using these two methods on the other hand, revealed a value of 1.42E-21, suggesting a significant difference in the two methods. This is an inference made through the very low p-value, which shows that the probability of the two populations being the same is extremely low. Similarly, the Pearson’s r correlation revealed values of 0.16 for temperature and for 0.66 heart rate. Design Flaws and Recommendations Experimental Design of Own Device
