INMGT422 - 01 Quality Engineering
Experimental Design Project
Project: The project requires teams of students to conduct a 23 factorial design experiment with 3 replications to determine which design factors affect a determined response variable.
I. The Factors and the Levels and data collection
A: Low (-) or High (+)
B. Low (-) or High (+)
C: Low (-) or High (+)
Response Variable: Deviation as described in project 1
II. Analyze results
Perform a 23 factorial experiment. Clearly label all the data values. Test for 95% significant effect of each of the main factors, the two-way interaction and the three- way interactions
Plot and analyze residuals and label all graphs
1. Residuals Histogram
2. Residual vs. Test order
3. Residual vs. Predicted Values
4. Residual vs. Levels of each factor (3Plots)
III. Written Reports
Write a brief summary of your design. The results of your experiment should include the followings
1. Detail description of design, data collection method, testing order, factor levels and discuss any common causes and how it will affect the results.
2. Describe the analysis performed
3. State the model as a function of the design factors
4. Analyze the residual plots and make conclusions about the accuracy of the model.
5. What follow up experiments would you recommend and why
