Qual + Qual Are kinds entangled? Mosaic Chi-square / two proportions
One Qual vs “more than half” Is this share rare? Bar / waffle One proportion

  • Do not average Sex, ChestPain, degree, helmet, immigrant, ethnicity.

  • Do not run ANOVA on Panel B.
  • Do not treat area in the Scottish file as a map.

  • CardioDataSets (Cáceres Rossi): heartdisease_tbl_df, cardioRiskFactors_df, scottish_CVD_df, cardiac_failure_df
  • openintro: infmortrate, sowc_child_mortality, bdims, yrbss, gss2010
  • gapminder: gapminder
  • AER: GSS7402
  • Files pulled via Rdatasets (Arel-Bundock)

NHANES and NFHS-5 / malariaAtlas were the preferred A and India-C objects. They are not in this zip because they need extra packages or an API. Group 3 A is a body-measure stand-in. Group 5 C is Asia-only gapminder, not district NFHS.
