The subjects will not know that they are being tested with gum as the treatment. Of course they will know they are chewing gum, but they will not know the other group is not. This goes for the control group as well. They will not be made aware that they are the control, or that the other group is chewing gum.]]> 2018-04-11 17:22:41 UTC https://padlet.com/erste403/98glh8jb3vdr/wish/250835026 erste403 https://padlet.com/erste403/98glh8jb3vdr/wish/250837543 Matched Pair- we will match subjects based on gender, gpa, field of study, and testing ability. We will then use one person from each pair as the control, and the other as the experimental. This will be randomized to erase bias. This will reduce the possibility of lurking variables in the study because the experimental units are so similar.]]> 2018-04-11 17:26:42 UTC https://padlet.com/erste403/98glh8jb3vdr/wish/250837543 erste403 https://padlet.com/erste403/98glh8jb3vdr/wish/250839493 The sample size in our experiment was 52 so the margin of error is 14.1%]]> 2018-04-11 17:30:07 UTC https://padlet.com/erste403/98glh8jb3vdr/wish/250839493 erste403 https://padlet.com/erste403/98glh8jb3vdr/wish/250841218 To replicate this study, we could get another group of 52 students from a different school to verify it’s statistical significance.]]> 2018-04-11 17:32:44 UTC https://padlet.com/erste403/98glh8jb3vdr/wish/250841218 erste403 https://padlet.com/erste403/98glh8jb3vdr/wish/251644754 We offered all 52 participants a $50 gift card for participating in our study which cost us $2,600. Our team of 4 reasearchers are given a one time payment of $500 which is $2,000. We provided the 26 pieces of gum which was 16 cents a stick (total $4).

We found that chewing mint gum improved test score for females by 3.15 points and males 2.6 points. We made millions selling our reasearch to gum companies and it is now used in gum advertising to college students. College students now have a budget for gum and sales go up during finals and mid-term week. ]]> 2018-04-13 17:25:01 UTC https://padlet.com/erste403/98glh8jb3vdr/wish/251658480
