Lab 2 Rubric
Total: 21 points
Each row is scored from 0–3 points based on the criteria.
| Lab Activity | 3 points | 2 points | 1 point | 0 points |
|---|---|---|---|---|
| Restate research question | Clearly and concisely restates the research question using the provided format | Restates question with minor clarity or format issues | Restates question but with vague or incorrect structure | Research question is missing or unclear |
| Make sure variables are coded correctly | Uses class() or map() correctly for all 11 variables; accurately recodes variable types and sets reference levels |
Mostly correct use of functions; recoding has minor issues | Incomplete or partially incorrect variable type checking or recoding | Does not check or recode variable types |
| Consider potential confounders and effect modifiers | Completes all entries with thoughtful classification and 1–2 sentence reasoning | Completes most entries with reasonable reasoning | Incomplete table or reasoning lacks clarity | Table is missing or mostly incorrect |
| Create contingency tables for categorical predictors | Correctly creates tables for all categorical predictors; identifies small cell counts | Creates most tables; identifies some small cell counts | Tables are incomplete or interpretation is unclear | No contingency tables created |
| Bivariate exploratory data analysis | Uses ggpairs() and clearly identifies predictors with visual trends |
Uses ggpairs() but interpretation is limited or unclear |
Attempts ggpairs() but contains errors or lacks insights |
No exploratory analysis completed |
| Fit simple logistic regression | Correctly fits model with glm(); displays and interprets unadjusted odds ratio |
Model is mostly correct; interpretation is basic or slightly unclear | Model or output has major issues; interpretation is missing or incorrect | Model not attempted or entirely incorrect |
| Plot the predicted probability | Accurately plots or tables predicted probabilities with clear labeling and formatting | Produces plot/table with minor issues in clarity or accuracy | Attempt made, but result is confusing or incorrect | No plot or table presented |
