# Final Project

** Final Project **- 100 point assignment (20% of the course grade)

11/1-11/8 Assigned in class

11/10 Proposal due (5 points) 1 per team

11/22 Collected data due (with a photo) (10 points) 1 per team

12/6 Written part due - **2 page limit** (60 points) each person

12/20 Oral presentation day (25 points) 1 per team

-------------------------------------------------------

**Proposal** due 11/10

A paragraph describing the designed experiment. Describe any factors and levels. What type of design, how many replicates, how many blocks or nested factors? How many test units you will need?

A second paragraph describing: H0, the type of analysis you plan to use (eg. ANOVA and a distribution-free test) and the three assumptions that need checking for ANOVA. Also, include the alpha value you are going to use.

Project options: Nested (treatment and sub-treatment), cross-over study, blocked (one treatment and one block), 2-way (2 treatment), 2^k factorial (k=3), repeated measures (one treatment), maybe one-way ANOVA unbalanced design, maybe regression,...

-------------------------------------------------------

**Collected data** due 11/22

- a table or chart with the data values and factors and levels

-R vectors of how the data will be entered. For example, if I have a treatment variable with two levels and a blocking variable with 4 blocks, then y=c(2,5,4,3,2,5,6,3) and treatmentA=c(1,1,1,1,2,2,2,2) and blockB=c(1,2,3,4,1,2,3,4)

-a picture of the data collection process

-3 to 5 sentences describing how data was collected and any randomizing considerations

-----------------------------------------------------

**Written Report** due 12/1 (one per person)

Be specific - start with your proposal paragraphs. Describe the data collection. Give the analysis output, conclusions, assumption checks, and also a distribution-free test. You may need to include a boxplot or Tukey test to determine which level(s) of the treatment are the best. Anything required for the slides should be in the report. (attach all R code on a separate sheet). Please also attach your graded proposal and graded data collection pages as well.

-------------------------------------------------------

**Oral presentation** (exactly 7 slildes) (120 minutes for 16 projects - 5 minute max. )

- Type of experimental design used and explain the experiment (treatments, blocks, levels, repeated measures…)
- A photo(s) of your data collection
- Define any statistical terms used (nested, blocks, treatment, levels, sphericity, )
- Describe H0 practically and show ANOVA results (H0 in words, ANOVA table, retain/reject)- code that produced it
- Show results of the 3 assumptions, is ANOVA a valid method?
- Explain and show results for one distribution-free test (Ch12)
- Make real world conclusion (boxplots and Tukey test as needed)

*you will be required to listen to the other presentations and give feedback as part of your grade.
