Inferential Statistics
Experiment 1 (Humans)
Explanation: We chose to utilize an ANOVA for this data set, because there were more than two groups being tested.
0mg v. 5mg
TTest: 8.60E7
Adjusted PValue: 8.33E3
Significant: Yes
5mg v. 10mg
TTest: 3.02E5
Adjusted PValue: 8.33E3
Significant: Yes
10mg v. 15mg
TTest: 6.48E8
Adjusted PValue: 8.33E3
Significant: Yes
0mg v. 10mg

0mg v. 15mg
TTest: 1.39E8

5mg v. 15mg
TTest: 1.57E8
Adjusted PValue: 8.33E3
Significant: Yes
Experiment 2 (Rats)
Explanation: We chose to utilize the unpaired TTest, because we where looking to determine whether there was a significant statistical difference between two completely separate data sets.
P= 0.87
13% Confidence
Summary/Discussion
The human experiment showed that as dosage was increased the inflammotin increased as well. However, the variability also increased as dosage increased. All trials were declared statistically significant.
Our data for rats showed very poor yields. We received a 13% confidence from our Ttest, which is very bad. When experimenting we aim for 95% therefore our data was not statistically significant. Some potentially sources of error include our smaller number of subjects and our drastic change in dosages without intermediate dosages.
Overall, even though there was no clear response in rats most likely due to the smaller sample sizes and lack of intermediary dosses, the human tests displayed a significant increase in the amount of inflammotin produced.
