Of course, there is a blatant lurking variable in that students who did better could be due to older age, therefore greater knowledge and experience with school work.]]> 2018-10-21 15:14:41 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295189260 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295190287 The control group of this study is another set of 10 teenagers, five of which who are 15, the youngest age of the subjects in the study, and five of which who are 18, the oldest age of the subjects in the study to better compare how age may or may not effect the study.]]> 2018-10-21 15:23:05 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295190287 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295190735 We are not able to conduct this experiment with blind subjects, as they all already know that they are taking an online class at two different times of the day, and they know the purpose of the study. This study also does not have a double blind either as the team has access to the grades and achievements that each subject has had in their class.]]> 2018-10-21 15:27:19 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295190735 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295191276 For this study, we are using a crossover design in where after the period of morning and late afternoon class times, for one week the subjects will do their work in the middle of the two designed times at 11:00 am. This will allow us to determine if morning has a negative affect and late afternoon has a positive affect on the subjects work, or if time of day is irrelevant to how well the subject does in school.]]> 2018-10-21 15:32:27 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295191276 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295192070 We are conducting this experiment with teenagers 15-18 (high school students), creating a margin of error of 22%. Although a 22% margin of error is sizeable, it would be impossible to conduct this study on the 15,000,000 high school students in the United States as it would consume an impossible amount of time and resources to do so.]]> 2018-10-21 15:38:48 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295192070 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295193180 To replicate a study such as this in the future, we could do so by creating a larger subject pool, whereas we study 100 students in contrast to the 20 we used. We could also set filters, such as only studying teenagers who are 15 years old, or only studying teenagers who are 18 as to create a decreased difference in age and achieve better results. In order to validate and ensure accurate reuslts, a replication of this study is very likely to be needed.]]> 2018-10-21 15:48:21 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295193180 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295193584 2018-10-21 15:51:56 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295193584 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295194984 The decrease in quality of classowork according to time of the day displayed a significant difference. The average class grade for the time of 7:30am resulted in a 74% average, or about a C in the class, whereas the average for classwork for 2:00pm was an 89%, or a B+. This shows that students tend to better later in the day as they were allowed more time to wake up and intelligently use their brain.]]> 2018-10-21 16:03:12 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295194984 druga521 https://padlet.com/druga521/qlncyq6w368w/wish/295195546 For our team of 10 researchers who worked a total of 30 hours, we paid each person $12.50/hour. There was no other cost as the subjects were volunteers to the experiment and the classes were set up by the colllege educated research team. Therefore:

Salaries: 10 x 12.50 x 30 =$3,750.
Total Cost: $3,750

We received the same results in that earlier class times negatively affect a student's class grade. In the future, we can potentially use these results to push school starting times back as to optimize a student's full potential to earn better grades.]]> 2018-10-21 16:14:49 UTC https://padlet.com/druga521/qlncyq6w368w/wish/295196375
