The remaining 150 people were to follow the same instructions but with decaf coffee instead prior to the memory test ]]> 2019-04-17 14:51:49 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352311900 becor358 https://padlet.com/becor358/fsosq2l6m0zc/wish/352315455 We found 300 men and women from the ages 18 to 65 who enjoy drinking coffee at least once a day per day. All were given gift cards to Starbucks for a 4 week commitment. ]]> 2019-04-17 15:01:52 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352315455 becor358 https://padlet.com/becor358/fsosq2l6m0zc/wish/352315915 Our explanatory variable was which treatment each unit received.

We also checked the balance of their gift cards to confirm that they stuck with the program. ]]> 2019-04-17 15:06:41 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352317304 becor358 https://padlet.com/becor358/fsosq2l6m0zc/wish/352320590 Our control group is the 150 participants who will NOT have caffeinated coffee in their day. We do have a placebo, and it is the decaf coffee. The participants will not know who receives what. ]]> 2019-04-17 15:13:45 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352320590 srben109 https://padlet.com/becor358/fsosq2l6m0zc/wish/352322191 We will replicate this study in the future using 300 new subjects. We may add multiple new treatments to our study including green tea. This will validate our results confirming their significance. ]]> 2019-04-17 15:17:22 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352322191 becor358 https://padlet.com/becor358/fsosq2l6m0zc/wish/352324017 We were able to blind our subjects because they were not aware of they were given decaf coffee or  caffeinated coffee. There are many Starbucks around nowadays so it is not very likely that they’d all end up at the same one at the same time. There is also a double blind because we are not aware of who will be getting what type of coffee. ]]> 2019-04-17 15:21:56 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352324017 becor358 https://padlet.com/becor358/fsosq2l6m0zc/wish/352324238 We had a few local Starbucks stores give us a list of 300 people who drink and purchase coffee often. We numbered them all and used a table to select 150 people for each treatment group. Potential lurking variables are age, amount of sleep, diet, and schooling. By randomizing, we can deduct the impact of these. ]]> 2019-04-17 15:22:29 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/352324238 srben109 https://padlet.com/becor358/fsosq2l6m0zc/wish/359308797 We found that those given the caffeinated coffee prior to the memory test scored an average of 85% on the memory tests, while those in the control group score 60% on average.]]> 2019-05-13 02:45:46 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/359308797 srben109 https://padlet.com/becor358/fsosq2l6m0zc/wish/359310445 We randomized our 300 participants and the results gave us a difference of 25% in test scores which cannot be achieved by chance therefore making our results statistically significant]]> 2019-05-13 02:55:15 UTC https://padlet.com/becor358/fsosq2l6m0zc/wish/359310445 srben109 https://padlet.com/becor358/fsosq2l6m0zc/wish/359310871 We published our findings in a medical journal.
