## Results
## Analysis
For the heart rate, the T-test showed that there was no significant difference among the means of the blood pressure cuff and the Spree headband, as the p-value was greater than 0.05. The Pearson's R showed that there was a weak positive correlation between the variables. A T-test was used because there were only two sample groups being compared.
For the heart rate, the T-test showed that there was an extremely significant difference among the means of the thermometer and the Spree headband, as the p-value was much smaller than 0.05. The Pearson's R showed that there was very little correlation between the variables. A T-test was used because there were only two sample groups being compared.
## Summary/DiscussionWhen analyzing the equipment used for the experiment, a few flaws were recorded. The most apparent flaw with the Spree technology was its inability to give a numerical statistic for the body temperature reading. Temperature was given in "levels" which was unhelpful when trying to analyze the difference between the thermometer and the Spree temperature readings. The second flaw recorded was with the Blood Pressure Cuff. The equipment had to be held in a very specific manner for it to record temperature and heart rate properly. Occasionally, there would be incorrect readings from the cuff because of the way it was held.
## LAB 3B WRITE-UP## Target Population and NeedOur product, SmartSole, is an insole for shoes that acts as both a pedometer and a pressure sensor for feet. Our target population would mainly be athletic runners, as this device would be helpful especially for gauging the pressure of their feet to identify if they are running incorrectly. SmartSole would also be helpful for people going through podiatric therapy or people with walking issues. Not only would SmartSole help correct their walking patterns, but their step and pressure information would be able to be shared with doctors through a cellphone app. The easy-accessibility of this information is a convenient, innovative way for consumers to constantly monitor their walking patterns.
## Device DesignSmartSole has a sleek design that comes in many sizes and can easily slip into any shoe. The insole comes with multiple built-in pressure sensors to measure the pressure of the entire foot.
## Inferential Statistics
## GraphThe graphs of the two data sets show that there is no significant difference between the two devices. This is because the p-value (0.995460375) is greater than 0.5. This proves that the SmartSole is just as reliable as the HTC Vive in counting the number of steps taken. The graphs of the two data sets show that there is no significant difference between the two devices. This is because the p-value (0.981718567) is greater than 0.5. This proves that the SmartSole is just as reliable as the Foot Plantar Measurement System in measuring the pressure of the ball of the foot. The graphs of the two data sets show that there is no significant difference between the two devices. This is because the p-value (0.985335871) is greater than 0.5. This proves that the SmartSole is just as reliable as the Foot Plantar Measurement System in measuring the pressure of the heel of the foot. The graphs of the two data sets show that there is no significant difference between the two devices. This is because the p-value (0.987799691) is greater than 0.5. This proves that the SmartSole is just as reliable as the Foot Plantar Measurement System in measuring the pressure of the outer side of the foot. |
