I want to show my students how Central Limit Theorem works in the real word examples.

More precisely, I want them to plot histograms and make Kolmogorov–Smirnov using SPSS.

I have already prepared artificial data using VBA. However, I would also like to do test on real data.

The data I wish to posses are:

  • IQ scores
  • noise in signal

I spend good amount of time browsing Google and open data sites, but I didn't found nothing useful.

Request: Can you help me with finding such data?

Side question: Do you have some tips for how should I browse for such data?
