We are at least 95% confident that there is a significant difference between the spree headband and the thermometer, the t-test value was 1.226E-32 with an alpha of 0.05. However, there was diminutive correlation between the spree headband and the thermometer according to the Pearson’s r coefficient of 0.208. Furthermore, there was no significant difference between the spree headband and the pulse oximeter.
The spree headband displays temperature as a color that corresponds to a range of temperatures, this leads to less accurate temperature readings and misinformation to the customer. An improvement on this technology would be to give number values for temperature instead of a range; this change would be more accurate and the customer would be more informed.

Analysis

For Temperature

T-test = 1.226E-32

T-test < 0.05 There is a statistical difference between the spree headband and the gold standard.

The Pearson's r coefficient is 0.208 indicating very little correlation.

For heart rate

T-test = 0.657460772

T-test > 0.05 There is not a statistical difference between the spree headband and the gold standard.

The Pearson's r coefficient is 0.69 indicating they have positive correlation.



Summary/Discussion

We are at least 95% confident that there is a significant difference between the spree headband and the thermometer, the t-test value was 1.226E-32 with an alpha of 0.05. However, there was diminutive correlation between the spree headband and the thermometer according to the Pearson’s r coefficient of 0.208. Furthermore, there was no significant difference between the spree headband and the pulse oximeter.

The spree headband displays temperature as a color that corresponds to a range of temperatures, this leads to less accurate temperature readings and misinformation to the customer. An improvement on this technology would be to give number values for temperature instead of a range; this change would be more accurate and the customer would be more informed.
