Than they re randomly selected and split in to two groups equaling 250. ]]> 2017-11-13 14:44:19 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206256952 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206262086 Once the groups are randomly split up into two groups, one of the 250 students will be given 8-10 hours of sleep before they are given a test. The other 250 students will be only given 4-6 hours of sleep before they are given a test. ]]> 2017-11-13 14:51:39 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206262086 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206263542 The explanatory variable is how much sleep each group was given. ]]> 2017-11-13 14:53:31 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206263542 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206266253 After all 500 students take all five tests, their scores will be calculated by their group and averaged. ]]> 2017-11-13 14:57:09 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206266253 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206269760 If students use substances that help them wake up and be more alert; like coffee, energy drink, or other substances could alter their performance on the test. ]]> 2017-11-13 15:01:52 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206269760 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206271074 Students who receive 8-10 hours of sleep will be considered the control group because it is reccomeneded to get at least 8-10 hours of sleep. ]]> 2017-11-13 15:03:47 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206271074 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206272724 To alter this experiment as a blind experiment students will not know the time of the alarm until it rings.

Taking a new 500 students with all ranges of gpa and give them sufficient time to sleep and little sleep. This will make sure no lurking variables effected the data. ]]> 2017-11-13 15:09:04 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206275508 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206277254 To create a randomized block design students will be split up by their gpa percentage. To make sure that students who have a higher gpa are not skewing the test average in minimal sleep as well as students with low gaps but enough sleep. ]]> 2017-11-13 15:11:06 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206277254 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206526769 With our sample size of 500, our margin of error is 10.8.

Students who did get 8-10 hours scored around the 80's, students who got 4-6 hours scored the 50's.]]> 2017-11-14 00:19:46 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206531857 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206532206 Our experiment was statistically significant because we found that the amount of sleep drastically alters test scores no matter the student's gpa.]]> 2017-11-14 00:22:28 UTC https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206532206 mnbai641 https://padlet.com/mnbai641/kef3a3rm1cqs/wish/206532309 Our results were used in many districts for lowering school starting times.
