There were 60 in each grade level. All were given a math test that was based on their math level. ]]> 2017-11-06 19:27:08 UTC https://padlet.com/hbvin759/tw354znctx1p/wish/204079560 hbvin759 https://padlet.com/hbvin759/tw354znctx1p/wish/204081756 The 60 students per grade level are randomly split into 3 groups of 20. Group A is assigned to take the test in a cold room. Group B is assigned to take the test in an average temperature room. Group C is assigned to take the test in a warm room. ]]> 2017-11-06 19:30:37 UTC https://padlet.com/hbvin759/tw354znctx1p/wish/204081756 hbvin759 https://padlet.com/hbvin759/tw354znctx1p/wish/204086254 The explanatory variable is the temperature of the room, whether it’s cold, average, or warm. ]]> 2017-11-06 19:38:25 UTC https://padlet.com/hbvin759/tw354znctx1p/wish/204086254 hbvin759 https://padlet.com/hbvin759/tw354znctx1p/wish/204086786 At the end of the testing period, every group’s test scores are averaged. ]]> 2017-11-06 19:39:28 UTC https://padlet.com/hbvin759/tw354znctx1p/wish/204086786 hbvin759 https://padlet.com/hbvin759/tw354znctx1p/wish/204087799 The control groups is each Group B per grade level, which is the group assigned to the average room temperature. ]]> 2017-11-06 19:41:22 UTC https://padlet.com/hbvin759/tw354znctx1p/wish/204087799 hbvin759 https://padlet.com/hbvin759/tw354znctx1p/wish/204090869 At the local highschool, we randomly selected students from each grade level and asked them if they wanted to participate.
