No Pearson's r-Value:0.690806 Inferential Stats Temperature Device P-value: 1.097E-21 Significant? Yes! Pearson's r-value: 0.1927980889 (Below minimum .4 required to conclude statistical correlation) Heart Rhythm Device P-Value: 0.661778 Significant? No Pearson's r-value:0.690806 Design Flaws and Recommendations Temperature Device The spree device produces results significantly different from the gold standard device. The p-value is much smaller than 0.05, meaning that the differences are in fact statistically significant. In other words, the data from the spree is very different from the gold standard. When comparing the two device measurements through the Pearson's value, which is 0.193, we see that it is much smaller than 0.4 (this is the minimum acceptable value showing correlation). From the data, we can infer that the spree device is inferior in quality to the gold standard and should not be sold in any market due to underlying technical problems causing the data to stray from those of the gold standard. Heart Rhythm Device The data provided in the test between the gold standard and the spree device have almost identical data recorded. The p-value is bigger than 0.05, which tells us that the data has little to no differences between them. Testing the reliability between them, we used Pearson's r-value and need to see if it reaches 0.4. The r-value found was 0.66 which explains that the spree device is similar and or more effective than the gold standard in terms of how it gets results. Letting it be sold as a heart rate tester would be much more useful to the public due to its replica data. =Experimental Design of Own Device Our experimental group would be people of both genders, of all ages that are suffering from high cholesterol related vascular disease. The gender sample will be divided on the gender division in US which is 50.8% female and 42.9% male. The ages will be as follows: youth 0-18, early adults 19-40, adults 41-60, and elders 60+. Once again the numbers in our sample will be divided based on amount of people of those age groups in US currently, which is 25%, 40%, 20%, 15% respectively. On top of this, the sample will also include a variety of severity of the diseases, ranging from only slightly above healthy levels of cholesterol to those seriously at life threatening levels which puts them at serious risk of suffering a heart attack or stroke. This will be the only group in the study as it will be a two tailed, paired, dependent test. Stats taken from 2010 Census (http://www.census.gov/prod/cen2010/briefs/c2010br-03.pdf).
