STA305/1004 - Project

Due Dates: November 11, 2019, 17:00 (Proposal) ; Dec 5, 2019, 23:59 (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:

0. Draft proposal of the experiment that you plan to conduct; (due: Nov. 11, 17:00 on

Quercus)

1. R Markdown document used to author your report, along with necessary data file(s);

(due: Dec. 5, 23:59 on Quercus)

2. pdf export of your report; (due: Dec. 5, 23:59 on Quercus) and

3. video presentation of the objectives, methods, results, and conclusions of your experiment.

(due: Dec. 5, 23:59 on Quercus)

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 2k

factorial experiment, where k ≥ 2, and the number of replications is

at least two. That is, the experiment should include 8 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.

Submission requirements.

You are responsible for submitting the following via Quercus by the due dates. The grading

rubric for the project is attached at the end of this document.

0. Draft Proposal of Experiment.

Due date: November 11, 17:00

• An R Markdown document (i.e., has .Rmd extension) and pdf export of the R Markdown

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.”

1

– The method could be stated as: “I will collect measurements of my ball speeds

while varying grip and stance at two different 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 effecting 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 final submission.

1. R Markdown document.

Due date: December 5, 23:59

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 files such as your observed data, you

must include them as well. Please keep your data files and .Rmd file 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 files as they are. (The TA will

install extra packages if necessary.)

We recommend using https://rstudio.cloud/ if you don’t already have RStudio and/or

LATEX installed on your computer.

An introduction to R Markdown is available on the course web site.

2. PDF report.

Due date: December 5, 23:59

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

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 effect; confidence intervals for the true values of effects;

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.

Due date: December 5, 23:59

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 profile 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.

Submission Instructions.

1. Submit your report and analysis including the PDF document, .Rmd file, and any

associated data files under Project: Report.

2. Submit your video presentation under Project: Video. You may use Quercus’s built-in

media recorder or upload your own video file. The uploading process may take a few

minutes.

Notes on video submission.

• If you are using a Mac, the Quercus media recorder submission page may not work on

your Safari browser. The recorder works fine with Chrome or Firefox on both Mac and

PCs.

• Beware that the Quercus media recorder doesn’t allow pauses but you are able to

retake your videos as many times as you want.

3

• Quercus accepts media file uploads of size up to 500MB if you are uploading a file.

The supported file types for playbacks are FLV, ASF, QT, MOV, MPG, MPEG, AVI,

M4V, WMV, MP4, and 3GP. If you upload any other file types, the TAs may not be

able to assign you a grade.
