## Descriptive Statistics

The Mean of the oral thermometer is 97.5661, and the Sensor had a mean of 96.13701. The difference between the two averages was 1.42909; so even though the sensor had errors and often times wasn't close to the oral thermometer temperature, overall there wasn't as much of a difference as one may expect. The standard deviation of the oral thermometer temperatures was 1.030571, and the sensor had a standard deviation of 1.640578. The oral thermometer is more centrally located around the mean because it has a smaller standard deviation; whereas the sensor has a greater standard deviation making it more spread out. The variance of the oral thermometer is 1.062077, and the variance of the sensor is 2.6915. Therefore it is easier to see that the sensor varies more, and is not as reliable as the regular oral thermometer.

## Analysis

Since the t-test resulted in a P value of 8.048E-18, and it is significantly smaller than .05 which indicates that with a 95% confidence it can be claimed that there is a statistical difference between the sensor and oral thermometer results. The Pearsons R-Value for correlation is 0.021715 there is little correlation between the sensor and oral thermometer readings. Therefore, the sensor was inaccurate and unreliable.

## Summary/Discussion

Both the oral and the sensor temperature readings vary in accuracy. They both reached a low minimum average in degrees Farenheit, which is unprobable in the conditions of the experiment. The temperature readings were not always probable or consistent in a controlled environment. Some design flaws of the sensor are that the sensor lost connection multiple times throughout the readings, the readings were mostly innacurate and unreliable, and the placement of the sensor under the armpit can be varied in multiple subjects, making the readings inaccurate. Since the p-value and the T-test is less than .05 there is a statistical difference. Also since the correlation value is less than 1, there is a weak correlation between the two devices.

## Target Population and Need

The target population for the Temperature Crown would be anyone who needs their temperature taken, specifically for athletes. The Temperature Crown gives them a clear reading of their temperature to keep them safe. After a game, match, or event, an athlete can get immediate feed back on body temperature. For athletes involved in different sports, the temperature can be too high or too low. For winter sports athletes, or sports involving ice, these athletes can become lethargic if their body temperatures drop to low. For summer athletes, their body temperatures can become too high causing heat strokes or overheating. With the Temperature Crown, trainers and coaches can read their players body temperatures and keep them hydrated so they can keep their peak performance.

## Inferential Statistics

These inferential statistics support our claim that the Temperature Crown is substantially equivalent to a common thermometer. Our value from the t-test shows that there is no significant difference between the experimental data from the thermometer and the Temperature Crown, since it is much higher than the threshold of .05. Our value for the Pearson's R-value show that there is direct correlation between the two sets of data, to a degree of ~99.9%.

## Graph

In the graphs you can see the oral thermometer which represents our control group in orange. Then in the blue is the data from our tests of the temperature crown. The temperature was taken with both the oral thermometer and the Temperature Crown at the same time and the results were recorded. We took 30tests. The first 10 points are of a normal person in their normal home environment. The second 10 (11-20) where of the athlete playing basketball, still heat rising but in a controlled air conditioned environment. The last 10 (21-30) the athlete played football and once again 10 readings were recorded. The Temperature crown matched the oral thermometer exactly except for 1 out of the 5 readings resulted in the temperature crown being off by .1 degrees. This data is represented in the graph because, except for 6 points, it looks like there is only 1 line. This means that the headband (Temperature Crown) is extremely accurate.
