Mean Spree Headband Temperature: 102.9 degrees Celsius
Mean Gold Standard Temperature: 97.6 degrees Celsius
Mean Spree Headband Heart Rate: 92.82 beats per minute
Mean Gold Standard Heart Rate: 92.52 beats per minute
Inferential Statistics
The T-Test above shows a p-value that is too low. The heart rate cannot be properly calculated using the spree headband.
The T-test for temperature shows a extremely small p-value.
Analysis
By comparing the values of heart rate between the gold standard and the spree headband we find that there is not a statistical correlation between the two. The p-value found in the T-test showed that there might be no relationship between the two measurements but we cannot be sure since the value is less than 0.1. The gold standard is assumed to be as close to the true value as possible. The spree headband produces a measurement that is somewhat close to the true value but not acceptable enough.
Comparing the values of heart rate between the gold standard and the spree headband for measuring temperature we found a correlation between the two. The p-value was much lower than the accepted p-value that states that there is a correlation between the two measurements. The p-value obtained from the T-test between the spree and the gold standard was 4.06*10^-45 which practically insures that the spree headband will not get the same results as the gold standard.The low p-value obtained also implies that the correlation between the spree and the gold standard rarely occurs mainly due to random sampling. This then makes it difficult for the same results to be obtained in the event of repeating the experiment.
Summary/Discussion
The variance between the Spree headband's measurements of body temperature and heart rate compared to the gold standard is too high to be acceptable. Our group has come to the conclusion that modifications need to be made to the Spree headband in order for it to measure body temperature correctly.
