Heart rate

## 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 Pearsonâ€™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.

## Target Population and Need

Our target population is wearable fitness device users and athletes.

The main demographics includes people 18 to 34 both male and female.

"Nearly one-third of US smartphone users, or roughly 46 million people, accessed fitness related apps in January of 2014. This usage grew by 18% year over year." http://www.wearables.com/who-are-fitness-wearables-users/#sthash.lZ9mPKLz.dpuf

Many sports teams are using wearable fitness devices to track their performance and then sending the data to their coaches, trainers, and players for analysis.

"Biometric sensors and GPS trackers developer Catapult Sports is currently working with 515 teams around the world ...... The NBA said in February it is testing out the technology in its D-League, making it the first U.S. professional sports league to use performance analytic devices in a game." http://www.biometricupdate.com/201410/professional-sports-teams-and-athletes-driving-wearable-technology
