Hi all,it's time to start thinking about and filling out project proposalforms.there is an example on course webpage and ?also at the COURSE RESERVES?at the D H Hill websitelib.ncsu.eduNOTES and FORM: (some old project titles below)\project partner can be from other section I am teaching so sections002, ?005and 601 people can be project partnersyou can do the project alone or you can look for a partner at "messageboard"from course webpage left frame=========================================a max of 3 people per project group===========================================the form for your project proposal is at the website (also by clicking onproject on course webpage) out the form and email tobmasmith@stat.ncsu.eduFill out at least items 1-9 below and paste into an e-mail to the instructor.?1. Name(s) ____________________________________2. Title and Brief description of experiment:3. The response variable is ________________and is measured inunits of ________________.4. Factors:Factor 1 is:Its levels are:Factor 2 is:Its levels are:if neededFactor 3 is :Its levels are:What is your "experimental unit" ?? ? How many experimental units will be needed to run your experiment ??Draw the DESIGN MATRIX and indicate the random order that the trails will be run(if 3 replications then EACH cell has 3 numbers in it, those numbers are the order that combination of factors will be run)fill in the names of your factors and their levels, don't use generic level 1 , level 2, etc??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ? factor 2?????? ??? ??? ? ?? ?? ? ? level 1?? ???? level 2?? ??? ??? ? level 3?? ??? ??? ??? ? level 4??? ??? ?? ???? ??? ? ? ______________________________________________??? ? ??? ? Level 1 |_______|___________|___________|____________|??? ?? ?? ? Level 2 |_______|___________|___________|____________|factor1 Level 3 |_______|___________|___________|____________|??? ??? ??? Level 4 |_______|___________|___________|____________|use "sample" function in matlab to determine random ordering?and put order of runs in the matrix5. How will randomization and replication be used?6. How will you analyze the data? means table and ANOVA (lm with class variables,i.e., with?qualitative?explanatory variables) or regression (lm with?quantitativeexplanatory variables)?[ Note ALL project must have: stats output, side by side boxplots,mfit, mplot, and rplots ]you need to also show the model statement for at least 2 full (main effects and interaction) models in matlab or R.?both models should include main effect and interaction., typically one has response and other log(response) or sqrt(response)see the 4 examples if you are unclear how to do this.YOU NEED TO INCLUDE MODEL STATEMENTS WITH YOUR PROPOSALINDICATE FOR EACH MODEL WHETHER ANOVA OR REGRESSION7. Briefly what do you expect to happen?8. ?Are there any safety concerns? ?will you wear protective eyewear? gloves ? mask ?9.
