Goal

The goal of this assignment is to begin analyzing your collected data, producing visualizations, summaries, and your first regression model.

To Turn In

In existing Deepnote project create a new notebook called Preliminary Analysis and including your preliminary analysis. All members contribute to both writing and computation.

Assignment Deliverables

Your preliminary analysis should include the following components:

1. Research Question
   Restate your question and provide sufficient background so that all variables are clearly defined.

2. Sampling Reflection
   Discuss whether aspects of your sampling may limit generalization to all Islanders.

3. Visualizations (3–4 minimum)

   • Each plot must have accurate and descriptive labels.
     
   • Include at least one plot assessing randomization effectiveness (e.g., demographic balance across treatments).
     
   • Each visualization must be followed by at least one interpretive sentence—no “naked plots.” That is, each visualization must have a purpose.

4. Numerical Summaries

   • Provide descriptive statistics for relevant variables.
     
   • Each table or summary must be followed by explanatory text—no “naked tables.”

5. Regression Model

   • Include output from at least one regression predicting the response variable.
     
   • Provide a short interpretation (one or more sentences).

6. Reproducibility

   • All analysis must be in a single notebook with code integrated into the narrative. DO NOT write all your code at the top and then the text below.
