> So they had 39 people total. 20 meditators and 19 non-meditators. Of that, 3 non-meditators of 19 gave up their seat and 10 meditators of 20 gave up their seat.

Small numbers, but the effect size seems big enough that this would pass the (admittedly low) bar for p=0.05.

Incidentally, does anyone have a quick method for estimating the statistical significance of numbers like these?



You can do a student T test in Excel with TTEST(), I assume you have similar functions in OpenCalc.


OK, but is there an estimate I can do in my head? Or on the back of a napkin?
