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



=Experimental Design of Own Device

Our experimental group would be people of both genders, of all ages that are suffering from peripheral 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 divided like this: 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. This will be our first group. The sample size would be about 20 people. If the device works well in the legs, we can move into the heart. We do not want to be testing the device on the heart first because we need to know if it will cause damage to the blood vessels and if it actually works before we go into such a complex and vulnerable organ like the heart. If our device works in leg veins and successfully removes cholesterol, then we will form test 2 which will be performed on a second group. This group will also contain people of both gender and all ages. The second group will be composed of people suffering from Coronary Heart Disease. The people from test 1 and test 2 will be different. From this test, we will see whether our device is applicable in the area of the heart.
