Project Proposal (Video Presentation)
Due: March 15, 2024 by 11:59PM ET
Goal of the Assessment:
This assignment consists of two parts. The goal of the first part is to give you a head start with
your final project. This will be accomplished by finding an area of interest to study and realworld data to work with. The second part of this assignment will provide you with an
opportunity to conduct research in an area you’re interested in. Conducting research will help
you determine what has been accomplished regarding your question and to highlight the
importance of your proposal.
The stepsinvolved in completing this assignment encompassthe general process of proposing
a research question and will help to form the basis for a strong introduction section in your
final project report. Your task for this assignment is to prepare a video presentation that describes your
data and research topic of interest. Completing this assignment will also give youthe chance to think
about the appropriateness of generalized linear models (GLM) as a tool for answering your
proposed research question using your chosen data. Lastly, this assignment provides an
opportunity to getsome feedback on your research question that can be used to improve your
final report using peer reviews.
Assignment Instructions:
1. Decide on one (or a few possible) areas of interest that you may want to explore.
These areas of interest can be anything that matters or is of interest to you. Some
examples could be (but are not limited to) sports, medicine, public health, economics,
video games, literature, etc. Pick something that you truly care about.
2. Next, think about possible research questions you may want to study regarding these
areas of interest. What do you want to know about these areas of interest? For
example, you want to make sure that your question can be answered/studied using
generalized linear models. GLM is not applicable for all datasets. So, you’ll want to
frame your question to be something related to modelling a relationship or classifying
a categorical outcome based on thisrelationship. You’ll also want to consider whether
the variable of interest would allow the assumptions of GLM to hold.
3. After producing a research question, you will need to find some open-source data that
you may use in your data analysis. You want to make sure that the data you find has
both: 1) your response variable of interest (or has variables that could be used to
create that variable), and 2) any other variables you may want to use as predictors. By
looking for data online, you may realize you need to modify your research question
slightly or pick another one if you can’t quite find the data you’re looking for.
Alternatively, if you are having trouble finding data online but want to stick with this
research question, be sure to mention that you expect there to be many limitations to
the dataset because it doesn’t quite meet your needs. Step 4 can also help you decide
2
what predictors might be needed for you to answer your question.
To help you identify data for your research question, some examples of open data
sources are listed below:
o https://open.toronto.ca for freely accessible data from Toronto
o https://data.ontario.ca for freely accessible data from Ontario
o https://www150.statcan.gc.ca/n1/en/type/data?MM=1 for data collected by
Statistics Canada
o https://sports-statistics.com/sports-data/ for various sports-related datasets
o https://data.oecd.org for data on various country-level variables
o https://mdl.library.utoronto.ca for links to many other data portals through
the University of Toronto library
4. Once you’ve found your dataset and have decided on your research question, perform
a literature search about to learn more about your research question. A literature
search can be done by performing a search on the University of Toronto library website
(https://onesearch.library.utoronto.ca/) or other databases that feature scholarly
articlesto learn about anything related to your area of interest and research question.
Look for academic papers or published reports (i.e., preferably peer-reviewed work
that has been published in reputable scholarly journals, not websites, blogs, or news
articles, etc.) that studied the same research question or something related, that
describes you more about what you may need to consider in your analysis. In your
literature review, include academic papers or reports to justify why your research
question is important. Some other suggestions on performing a literature review
include:
o Focus on giving your reader a rough idea of how many academic papers have
studied your research topic (or closely related concepts to your topic). This
process of looking at the number of academic papers which describe a specific
topic tells your audience how popular the area of research is and how much
research has been done.
o Give examples from a few important papers about what was found or
discovered to be important in relation to your question. This can be important
variables, important results, surprising results, etc. The process of identifying
and describing important paperstells your audience that you are aware of prior
results and that you will be using these to plan your analysis.
o Think about how your research question fits into the general area of research
about your topic. For example, is your research question different from
research questions in other studies? If so, how? A novel research question
consists of either something that: 1) nobody has studied before, 2) studied
using a different methodology/study design, or 3) studied in a different population.
The process of examining if your research question is novel tells your audience
that you see the importance of what you are researching and can frame it
against what has already been done.
Attached here are some additional library resources which may be helpful for
performing a literature review::

details about searching for articles related to your question
o https://guides.library.utoronto.ca/citing for details about why and how to
cite your references
o https://guides.library.utoronto.ca/c.php?g=251103&p=1673071 for help
getting the correct citation format
5. After completing a literature review, perform a short exploratory data analysis of your
chosen dataset. You will want to focus on identifying anything that you may need to
consider moving forward. This includes identifying in your dataset:
a. potential confounders,
b. statistical outliers of the exposure and the confounders of interest (if
continuous),
c. variables with high spread or observations that don’t make sense, and
d. missing data
For section 5, you want to make sure you specifically mention the presence of any of
the characteristics in 5a-d (or lack thereof) and what this means for the analysis you
will eventually perform. For example, this may include describing how any of the
characteristics in 5a-d might cause problems (or not) with the results of GLM or
generalizability. You will need to present univariate or bivariate numerical and/or
graphical summaries describing the variables. Choose the options that highlight the
features of the data that you want to point out but will also let your reader clearly
understand the data that you will be working with.
Guidelines for Picking a Dataset
o Government data portals often contain many datasets about diverse topics – if one
dataset doesn’t have all the variables you might want to consider, feel free to
combine different datasets together
o When combining datasets, make sure that each unit being measured isthe same
in both datasets (i.e., it’s reasonable that both measurements are on the same unit)
o There are many data repositories online – if you find a dataset there that is of interest
to you, you MUST ensure that your question is different than what the dataset was
originally used for.
o YOU MAY NOT use any dataset that is part of any R package or library, or that is
contained in a textbook. If you’re not sure, please ask the instructor.
o You will need to make sure you have enough variables to be able to showcase the
statistical methods that you will learn later in the course. Some topics the teaching
team will require include model validation and model refinement so please ensure
your dataset has at least 5 predictor variables.
o You will also need to make sure you have enough observations to be able to validate
your model, which will involve splitting your dataset into two roughly equal parts.

Presentation Content Requirements:
Your presentation should satisfy the following requirements:
o The presentation should be organized clearly (consider using headings or sections)
and include the following information:
a. Your research question, why you chose it (i.e., why it’s of interest to you), and
why it may be of interest to others.
b. Summaries of academic papers related to your question or topic, highlighting
similarities/differences to what you propose, and how you will incorporate this
knowledge into your model/project.
c. Details and summaries on your chosen dataset including the variables
collected, the number of observations and anything that stands out in the data
that would need to be addressed/investigated further in your analysis.
d. A discussion about how and why a GLM fits your chosen data. This will allow
you to answer your proposed research question, as well as whether you
anticipate any problems that may arise in your analysis from EDA.
e. References for where you located the data, and your background research on
your topic
o The presentation should be presented for an audience that has some statistics
background but is not necessarily familiar with the area of your research question or
