Is the difference between say 97 and 101 IQ really significant?
I'd attribute the scores that are lower than 90 (or maybe 95, or 98, I don't know) directly to lackings regarding national education, but does fluctuation among the others really mean something?
- lmm 12y agoWith a large enough sample size small differences can be significant. It's bad practice to display a more precise IQ number than your confidence intervals, so I'll assume the differences are real.
