In this assignment, you will continue exploring the data, and create a readme document. This is an individual assignment.

  • Review good practices for readme and data documentation
  • First, consider the VWS Survey we used in class: Codebook, sample data Link it to your AI. (Can move to google drive. )
  • Second, choose a research question using the VWS data. It can be broad or specific. Ask AI for ideas.
  • What variables would you use to investigate the research question? Pick the most relevant ones (min 8, max 25)
  • Review survey timing and discuss consequences
  • Considering these variables only create a single README.md (in markdown).

The readme

In the readme, include:

  • key info on the dataset itself (you need to figure out what this key info is based on the lecture and examples)
  • key variables description
  • table with descriptive statistics for the 5 most important selected variables

To submit

  • README.md file. (lastname_firstname_dawai_week02_readme.md) (16p)
  • What advice would you give to a fellow data analysis student on using AI to create README documents? (lastname_firstname_dawai_week02_advice.txt) (4p)
    • List 2–3 pieces of advice based on your own experience using AI for this specific task.

AI use restrictions

  • Do not use AI to help you generate the advice. We want to hear your personal examples and reflections, not AI-generated suggestions.
