We did not know the individuals. We then went to school and surveyed 15 random students who don’t drink coffee. We got a total of 30 high school students who we surveyed. ]]> 2019-04-17 17:56:36 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352380675 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352382288 We chose the starbucks randomly but we had to get permission to use customers. We chose the individuals who drank coffee by the order they were in at the line. We then walked into different classrooms and randomly selected students who didn’t drink coffee. ]]> 2019-04-17 18:00:41 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352382288 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352385858 We went to starbucks and surveyed 15 students and asked them how they felt before they drank their coffee. We then were able to get their phone numbers and texted them to see how their energy was and if the coffee helped. We also asked 15 students at school how they felt their energy was without coffee. ]]> 2019-04-17 18:09:01 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352385858 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352386839 Our explanatory variable was If they drank coffee or not.]]> 2019-04-17 18:11:30 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352386839 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352388125 We measured how much energy the individuals had after they had coffee or didn’t have coffee. ]]> 2019-04-17 18:14:39 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352388125 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352388431 We randomized Starbucks as well as our school to make sure the locations were diverse. We still have a lurking variable which consisted of what size drink people had gotten and also how many shots of espresso people had gotten in their coffee. ]]> 2019-04-17 18:15:23 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352388431 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352389358 The control group is the people who had purchased coffee. The cases were the people who did not consume coffee. There was no placebo but we will be able to compare the data.]]> 2019-04-17 18:17:08 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352389358 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352390424 We chose not to have a blind study because our individuals were supposed to know how much they were drinking and how much energy they felt they had. ]]> 2019-04-17 18:19:22 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352390424 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352390446 We do not have a crossover design. We chose one weekend to collect data and we also had everyone at the same store. ]]> 2019-04-17 18:19:25 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352390446 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352391507 We determined it is not statistically significant because we had chose one store and one weekend instead of choosing multiple.]]> 2019-04-17 18:22:07 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352391507 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392249 This study could be replicated in the future but with an additional study of more stores included and different days. We may consider adding one size for everyone and we concluded that replication is going to be very important to validate our results.]]> 2019-04-17 18:24:00 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392249 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392772 We had 30 people who were experimented on. 15 had coffee and the other 15 did not. Each coffe bought was around 5 dollars which would come to an outcome of 75 dollars.]]> 2019-04-17 18:25:32 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392772 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392778 We ran this study with a sample size of 30 people. The margin of error is 18.3, this is a very large margin of error which gives us alot  of variety for how much energy they felt they had. ]]> 2019-04-17 18:25:33 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352392778 sesko836 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352393620 Overall, after results were concluded the 15 people who had consumed coffee were more energized and more awake then the ones who had no coffee consumed. We concluded that people with bigger sized coffee were more energized then people with smaller sized coffees. ]]> 2019-04-17 18:27:52 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352393620 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352394657 2019-04-17 18:30:38 UTC https://padlet.com/sawhi987/dx0wpgokj22c/wish/352394657 sawhi987 https://padlet.com/sawhi987/dx0wpgokj22c/wish/352395089 Our results show that people who drank coffee said their energy was in the highs and people who don’t drink coffee said they were in the lows.
