Your company has 3 different manufacturing plants in different cities across the country. In each plant you manufacture 3 different products, and they are all evaluated on Fit and Finish before being packaged for distribution and sale. Fit and Finish evaluated on 100 point scales. Each of your plants runs 3 shifts, and the production of each product is rotated throughout those shifts.

If you want to know if Fit and Finish vary by Plant and Shift, what type of analysis would you run?

1. Independent samples t-test
2. Paired samples t-test
3. One-way ANOVA
4. 2-way ANOVA
5. MANOVA
