I was free to set my hours a bit more flexibly. | Drdrdrq wrote: | N=45. Interesting idea though. | clircle wrote: | N=45 is relatively high power for simple analyses, like a | t-test (not sure if that's what the paper did). | | You can detect an effect size of 0.6 with 80% power when N is | 45. You can also detect a effect of 0.7 with 90% power at N=45. | | There are other things that can make results unreliable, like | p-hacking, but a sample size of 45 is not a sufficient | condition for bad science. | rossdavidh wrote: | So, I agree it's an interesting idea, and I think this small | study could hopefully spur more conclusive ones, but... | | 1) N=45 | | 2) based on "semi-structured phone interview" | | Neither of these is a deal-breaker, but what you'd really prefer | is some sort of objective measure of sleep quantity, and how it | impacted the person. Teenagers are, by and large, entirely aware | that when adults ask them questions, they are likely to draw | conclusions about policy towards teenagers. They want to sleep | later. How likely is it that they would admit it, if they didn't | really get any more sleep out of this? | | Not saying it's not true, or that it isn't an interesting idea to | try to put this "natural experiment" to work somehow, but I'm not | sure this is really enough to draw any conclusions, and I | actually already agreed with their conclusion before seeing this | study. | | A better method might be to compare home-school students to | public schools, or compare summer-break to school year, and to | use some more objective metric than a phone interview. | toyg wrote: | I wonder if the youthful predilection for "sleep late, be active | at dawn" is some sort of evolutionary adaptation. Night raids, | the young being tasked with the most annoying night-shifts... | | All pure speculation, but there must be something more than "kids | are lazy and then they 'grow' out of it" - if anything because | some people ( _cough cough_ ) never actually do. | mavhc wrote: | AIUI teenagers in USA start school early so they can reuse the | same school buses for younger children, it's a cost cutting | measure most of all | pxeboot wrote: | That is unrelated to the school schedule.
