Project Work Day

Pick 1 of the 3 proposed data sets and create the following in the report.qmd

– Introduction and data

– Methodology

– Results

– W+F

— update about section

— Respond to all issues from chosen data set

— Everyone is your group must have at least 3 commits

Introduction and data

– Do not copy and paste what you see about your data online

– Flush out where the data come from, how they were sampled, description of observations, etc.

– Challenge: Put more detail into the intro (even if feedback was not given)

Methodology

– How do you plan to answer your research question?

– Prediction? Inference? Both?

Adding Additional Variables

– Since multiple linear regression analysis allows us to estimate the association between a given explanatory variable and the response holding all other variables constant, it provides a way of adjusting for (or accounting for) potentially confounding variables that have been included in the model.

Results

– What are you finding out?

– Make sure that this is connected to your research question. It is easy to get excited and explore your data set. Make sure that all results you generate are in-line with the research question you have asked.

W + F

— update about section

— Respond to all issues from chosen data set

— Everyone is your group must have at least 3 commits

Tips + Tricks

– Ask questions early and often (to your groupmates; lab helpers; lab leaders; and the instructor)

– Do not break up this project into individual assignments. Each part of the project is everyone’s responsibility
