Group 2 Assignment Review
For this assignment, we will be submitting a webpage with the requested analysis of the data. The html link (only) will be submitted through blackboard. The webpage will be created with RMarkdown and analysis self-contained (i.e. all data manipulation, analysis, plotting, etc. should be done within R). The code that was used will be included and...

Design of Experiments
Project For Design of Experments For our Design of Experiment Project, we created three different parts which looked at three different design of experiments designs. The three different experiment designs that we preformed were a completely randomized design , a factorial design , and \(2^4\) factorial design. Completely Randomized Design ## #...
