Gender and Math - Methods

  • Compute the sample-weighted mean math score for girls/boys separately for each country.
  • Calculate difference in the means (boy - girl)
  • Compute ratio boys to girls taking the test
  • Do t-test separately by country, record unadjusted p-values
  • Sort countries from biggest difference to least, biggest gender gap in favor of boys to that in favor of girls
  • Plot difference by country, colored by significance, sized by proportion
