Actually an N=30 is sufficient to produce a normal curve and minimize error. everynametaken Send a noteboard - 03/04/2010 05:26:27 AM
I am wholly convinced that games as a medium aid learning and help children develop the skills and mindset of wanting to learn, but I'm really too lazy to argue that or back up my opinion at the moment, so take it with a grain of salt.

I am also wholly convinced that learning and academic achievement are not nearly as related as many people think.

I am also wholly convinced that yes, any kid that is allowed to utterly abandon themselves to any form of entertainment - or anything in general - will suffer academically. All things in moderation. Even academics.


Also, depending on the probability used in the hypothesis test and the effect size the power of the study may be large. Large sample sizes are not necessarily needed in statistical testing. The minimal needed sample size of 30 is based on the Central Limit Theorem.

P.S. I hope I don't come across as a dick here, I'm not lecturing or patronizing you, but I see sample size used a lot as a reason to discount results when it shouldn't be. :)

probably not if they're spending the same amount of time LadyLorraine - 17/03/2010 01:56:32 AM 696 Views
Hah. Not a very convincing sample size there. lord-of-shadow - 16/03/2010 11:54:44 PM 770 Views
too true. LadyLorraine - 17/03/2010 02:00:38 AM 717 Views
1500 data points are not needed to be representative. everynametaken - 03/04/2010 05:31:51 AM 864 Views

And anyway, any null hypothesis can be rejected with a large enough sample size. Burr - 10/04/2010 03:49:41 AM 810 Views
what? you mean if I don't do my scholastic work, my academic progress will diminsh? LadyLorraine - 17/03/2010 01:47:51 AM 731 Views

Damn! Now I have to get rid of my consoles! Beqi - 19/03/2010 12:31:22 AM 719 Views
why should you get rid of your consoles? LadyLorraine - 19/03/2010 03:07:38 AM 656 Views
The words "video game" can be replaced by anything with the same result. Mats Gambling Buddy - 19/03/2010 05:54:51 AM 773 Views

well if your parents never buy you new games... LadyLorraine - 19/03/2010 12:36:08 PM 660 Views
+1 for misspelling the phrase per se. Apparently Yahoo has now corrected that error. *NM* Ghavrel - 21/03/2010 09:23:04 PM 338 Views
That's pretty stupid. Type of game is very important. RugbyPlayingAshaman - 23/03/2010 03:47:16 PM 756 Views
While it may seem like common sense... everynametaken - 03/04/2010 05:39:59 AM 793 Views
