Project
For this project, each student - no groups allowed - will design, analyse, and communicate the results of a homemade replicated 2 k factorial experiment, where k > 2.
Each student is required to submit four items:
1. Draft proposal of the experiment that you plan to conduct;
2. R Markdown document used to author your report, along with necessary data file(s);
3. pdf export of your report;and
4. video presentation of the objectives, methods, results, and conclusions of your experiment.
Detailed description and requirements are provided below.
Description.
Each student is asked to plan and perform a homemade factorial experiment. The experiment must be a replicated 2 k factorial experiment, where k > 2, and the number of replications is greater than two. That is, the experiment should include 16 measurements at the minimum.
Students should start thinking about decide what they want to study. The number of possible topics is very large. We strongly recommend selecting a topic that you are interested in and will enjoy working on.
0. Draft Proposal of Experiment.
An R Markdown document (i.e., has .Rmd extension) and pdf export of the R Mark-down document that states your experiment's objectives, methods, statistical analysis plan.
{ The objectives should be concise statements about what you are hope to learn, and the methods are your plan for collecting the data. In the example of the baseball experiment in the introductory video [add link] the objective could be stated as: \What are the effects of grip, and stance on ball speed.";
{ The method could be stated as: \I will collect measurements of my ball speeds while varying grip and stance at two di erent levels each. I will vary my grip with placements of the index and middle fingers, open versus closed. The stance factor will be based on the height of the left leg during the wind-up motion. I will perform 5 repetitions in a randomised order since my arm may loosen up and/or tire out e ecting the ball speeds. The order will be radomised using an R script prior to the measurement session. I will also randomly pick a baseball from a ball
cart each time I pitch. It is well known that a baseball with worn out seams result in lower ball speeds. Finally, a friend will measure my ball speeds using a speed radar gun while I pitch following the radomised order.";
{ The statistical analysis plan is a brief description of how you plan to analyse the data, including which summary statistics and data visualizations you plan to include.
The draft will not be graded. If a draft with the content outlined above is submitted then you will receive full credit. TAs will give students feedback on their draft as soon as possible. The draft is an opportunity for you to receive early feedback on your ideas and plans so that you can incorporate the feedback into your nal submission.
1. R Markdown document.
You are required to write your report and perform your analysis in an R Markdown document using R. Submit an error-free R Markdown document (.Rmd file) that contains the R codes used to perform analysis. If your code requires extra les such as your observed data, you must include them as well. Please keep your data les and .Rmd le in the same directory to help accelerate the grading process. The grading TA must be able to run your notebook without an error on their machine after downloading the les as they are. (The TA will install extra packages if necessary.)
2. PDF report.
A maximum 4 page PDF report that contains the following sections. You are required to use R Markdown to create your report. However, the final PDF report must not include any R codes. (Include knitr::opts chunk$set(echo=FALSE) in your first code chunk to hide code chunks throughout your output PDF document.)
1. Description (1 page maximum). Include how and why you conducted the experiment. What do you hope to learn by doing this experiment?
2. Analysis of data (2 pages maximum). Include appropriate plots and calculations used to answer experimental question(s). These may include main effects and interactions, estimated variance of the e ect; con dence intervals for the true values of e ects; Lenth plot; or half normal plot.
3. Conclusions (1 page maximum). State your conclusions based on the results of your experiment in a paragraph or two.
3. Video presentation.
A video presentation of your study. Your video must meet the following criteria: In the beginning of the video, you must clearly present your student ID along with yourself. The grading TA must be able to identify you and your student ID number.
Failure to present your student ID will result in a 0 grade for the video presentation. We recommend that you update your Quercus pro le with a picture where your face is clearly identifable.
The presentation should not exceed 5 minutes. Any video beyond 5 minutes will not be viewed by the grading TA, and will not be considered when marking. In the video you should describe the objectives, methods, results, and conclusions of your experiment.
The video may be of any form, so be creative! For example, you may include clips of yourself conducting the experiment while describing the experiment - beware that the clips will also count towards your 5 minute limit.
