Bring a calculator that works. Bring pencils and erasers. All necessary formulas will be provided. The entire One-Factor ANOVA table and Two-Factor ANOVA table will be given, inclusive of formulas for SS, MS, and F I will give you the necessary tables: Tukey-T and F (as they appear on my web site). Make no marks on the tables. If you do, the cost is 25 cents per table or 2 points off the exam for each table marked. This is one good reason to bring and use pencils and erasers.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
