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. | 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.

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. | 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.
