Inferential Statistics

Body Temperature:

T-Test Value: 1.12E-8

Pearson R-Value: -0.054

Heart Rate:

T-Test Value: 0.326

Pearson R-Value: 0.560


The results for the comparison between the Spree temperature and the gold standard temperature show that there is no significant difference in these temperatures as the T-Test value is less than 0.1. The reason for this is because the Spree headband does not show the exact temperature, only colors that represent on single temperature, and there are only four colors. This lack of accurate, numerical temperature is a limitation of the Spree headband and could be improved by improving the thermometer aspect.

The results for the comparison between the Spree headband heart rate and the gold standard heart rate show that there is a significant difference between the two tests as the t-value is greater than 0.1. The heart rate component could be improved by finding a way to make the headband more accurate or by putting it in a different location on the body that has a more defined pulse.

The spree headband include a variety of design flaws. The most common problem was the headband continuously disconnected from the spree app on the cell phone. After the headband disconnected, the heart rate monitor would not record a reading for a couple of minutes while the other values were displayed on the spree app. A possible solution to this problem is to change the wireless connection between the spree and smart device to something else, like inferred, rather than using Bluetooth. The Spree device only had four levels of temperature to evaluate at which created a small deviation of body temperature from the limited possibilities.


Target Population and Need

Our target population is the "average Joe." The average American spends ten hours per day working and caring for children or others. Only 29% of American adults get the CDC recommended amount of muscle strengthening exercise per week. FEMS technology would help strengthen the muscles of average adults who do not have the time or energy to exercise as much as recommended.

Device Design

This device has the shell of a morphsuit with "smart skin" technology wired throughout the suit. It delivers precision amounts of electric stimulation to muscle groups throughout the body to contract muscles and stimulate muscle growth.


Inferential Statistics

Our statistics our taken from theoretical measurements of 50 participants doing the CDC suggested cardiovascular and muscular exercise for 6 months and 50 participants doing the recommended cardiovascular exercise and wearing the FEMS suit for 30 minutes, 3 times per week for 6 months. Participant lean body mass composition is measured every week and progress is recorded. T-test:7.49585E-06 Pearson's R value:0.984846026

The FEMS technology results in slightly higher lean muscle gain than regular exercise.
