Unless I am missing it, they don't report the results by gender, but they do by age. Is this suggesting that the results were identical across gender?

  > Is this suggesting that the results were identical across gender? I suppose you mean sex, since using genders for preschoolers would be ridiculous. Secondly no, it's not suggesting that. It's simply suggesting they may not have grouped their results by sex, maybe because that would have made the groups too small to yield useful data, or because they simply weren't interested in that. As an aside, you shouldn't post-factum partition your data by characteristics you did not set out to compare, because then you might try height, intelligence, hair color, etc. until you find some characteristic that yields differences of "statistical significance" even though you've just been trying them all until you found something that differentiated some groups by random chance.

    Why would age (3 groups), which they did partition on, be statistically significant but not sex (2 groups, assuming no intersex)?

      That's just not what I said.

        >maybe because that would have made the groups too small to yield useful data How would 2 groups be "too small to yield useful data" when 3 groups yield useful data.

          Because you would be subdividing again, which yields 6 groups. Also read my last paragraph about 'playing' with your data like that.

            >Because you would be subdividing again, which yields 6 groups No, it would be 2 groups if the single partition was sex. It would only be 6 groups if they also wanted to slice each group again by age, which is not what I'm asking. The 2 groups are not "too small" if 3 groups are not "too small." >Also read my last paragraph about 'playing' with your data like that. I did, and I think that's valid. However, it has no bearing on my point about the size of the groups.

          Maybe they were all boys.

            The sex split is within the first sentence of the study Abstract. It was 54% girls.

    I mean, if a part of the experiment wasn't "inspect the childrens' genitals" I think it would me more accurate to call the split a gender split rather than a sex split even if it results in the same groups.
