AnalysisTo get our results for this lab, we originally used an ANOVA test to get our p-values. Running this test was the equivalent, although more complicated, to a t-test. The p-values are very nearly the same from each test so both tests would give the same result, although the ANOVA requires more work. These tests were used to measure the effectiveness of newer products against the gold standard for the purpose of the device. Temperature measurements Based on the data the p values for the first inside temperature,second inside temperature and the outside temperature are 1.62E-34,6.76E-31 and 1.18E-71 respectively for the ANOVA tests which shows that there is significant difference between the oral thermometer measurements and sensor measurements since the p values are really small.There is a 99% chance that our results are right. BP measurements The P values for the lab measurements and post walk are 8.4E-14 and 2.7E-25 respectively which shows that there is a significant difference between the BP cuff measurement and the watch sensor measurements. Pulse measurements The p values for the lab measurements and post walk measurements are 5.5E-31 and 3.5E-79 respectively showing that there is a significant difference between the pulse oximeter measurements and the watch sensor measurements.
Summary/DiscussionTemperature The pearson's R value for the temperature measurement is -0.129 and this shows that there is no correlation between the sensor measurements and the oral temperature measurements when the measurements are taken inside or outside the lab. BP The pearson's R value for Bp the measurement is 0.412 and this shows that the two devices have no correlation when measurements are taken in the lab or after walking outside for 15minutes. Pulse The pearson's R value for the pulse measurement is 0.766 which shows that there is a slight positive correlation between the watch sensor and the pulse oximeter when measurements are taken both inside the lab and outside the lab for 15minutes. It can be concluded that since both devices yielded different results the sensor measurement is an inaccurate and unreliable way of measuring body temperature.
The sensor uses a Bluetooth to record temperature,and this makes it difficult to differentiate the temperature read out because other devices in the lab also use the Bluetooth too. Recommendations:
LAB 3B WRITE-UPBrain Activity Monitor: Back On Track--BAM BOT!Target Population and NeedTarget Population: It warns of negative impacts from mental illnesses, to help people focus and think more intelligently, and records brain activity. It is able to be programmed to different settings including: warning mode, active thinking/study mode, and monitor only mode.
Device DesignBrain Activity Monitor Band--BAM Band!
Inferential StatisticsThis is the T-test for the BAM-BOT compared to the gold standard. T test: 8.66899E-76 Pearsons R: 0.999987005 The tests were run using the same person testing both devises. the test consisted of scripted reactions to stimulus of music, math problems, reading, and critical thinking. Changing the stimulus every 10 min to get the brain waves to react to the stimulus. Between the two devises there was no statistical difference to note. The BAM-BOT has the same level of accuracy as the gold standard.
