That's a strange result and an even stranger study: most parents do not have 4 children. Is this perhaps skewed by only childs, since those definitely get most attention by parents and are thus likely to perform a little better than average?
In my case (I have a sister) the outcome was different too, I was a much better student.
- gus_massa 12y agoIf the raw data were available, it would be interesting to recalculate the statistics (something like last, last-1, last-2, last-3) and see if the last children is the smarter too.
- alkonaut 12y agoYou are probably right. One would hope that comparisons of children 1-4 are done on a sample of 4-child families only. Including single child families or 10-chile families obviously skews the attention parameter, not to mention it touches other factors such as the effect on parents' education on family size.
