From the 42 students, each will be randomly assigned into treatment groups of 14.

Group A will receive coffee that morning, Group B will receive decaf, and Group C water.

Every student will than be given a short math quiz, their scores being recorded.]]> 2019-04-18 03:24:42 UTC https://padlet.com/blkup639/uwk1i6b4cz9t/wish/352475946 blkup639 https://padlet.com/blkup639/uwk1i6b4cz9t/wish/352477158 This experiment is a blind because the two treatment groups don't know if their coffee is decaf or regular.

It would be a double blind if those administering the tests and collecting the results weren't aware either.]]> 2019-04-18 03:37:09 UTC https://padlet.com/blkup639/uwk1i6b4cz9t/wish/352477158 blkup639 https://padlet.com/blkup639/uwk1i6b4cz9t/wish/352477393 Group A will be given coffee
