If the math was solid, you'd have a point. But it doesn't, so you don't.

- mgamache 7y agoBecause you know more then the editors at Jama? Without explaining why?
- wysifnwyg 7y agoReturning to the math, I did the calculations and here is the margin of error for each group: 11%, 9%, 9%. Their common error (the overlapping region of area) is the interval 87.79-104.95. The IQ scores from each group (94.91, 96.29, 96.47) are well within that margin of error. If you perform a t-test on 3-Ca vs. 3-placibo you'll see that the difference is not statistically significant.
