Does temperature of classrooms effect test scores?]]> 2019-04-17 14:45:13 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352309432 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352310997 Experimental Units

Our experimental units were 60 random students who were juniors. ]]> 2019-04-17 14:49:19 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352310997 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352311994 Selection Method

The juniors were randomly selected by putting their already assigned ID numbers in a random number generator. From there they were randomly split into 3 groups, with 20 students in each group.]]> 2019-04-17 14:52:06 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352311994 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352313683 Treatments

We set the temperature of the cold classroom to 65 degrees Fahrenheit. The next classroom was the control and had no A/C, it remained at 75 degrees Fahrenheit. The last classroom was the hot classroom and was kept at 85 degrees Fahrenheit.]]> 2019-04-17 14:56:55 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352313683 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352314382 Explanatory Variable 

Our explanatory variable is the temperature of the classroom the students tested in.]]> 2019-04-17 14:58:55 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352314382 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352314908 Response Variable

We will score the tests to see how well the students did on the test, to see if the temperature had an effect.]]> 2019-04-17 15:00:28 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352314908 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352316903 Randomization/Lurking Variables

We randomized the students when splitting them into groups to ensure there was a variety in gender. We still have lurking variables like what temperature the students are used to or how each student is dressed.]]> 2019-04-17 15:05:33 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352316903 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352317378 Control Group

The classroom with no A/C will be our control. It will be at a neutral temperature of 75 degrees Fahrenheit.]]> 2019-04-17 15:06:52 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352317378 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352318561 Blind/Double-Blind

Our students will be blind in the experiment, so they won’t know which classroom they have before hand. We do not have a double-bling though, researchers running the experiment will be aware of which classroom is which and what group goes where.]]> 2019-04-17 15:09:57 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352318561 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352321608 Sample Size/Margin of Error

We are running this study with a total of 60 students. Our margin of error is 12.9 which is large. A larger margin of error is not ideal but gathering more students who are willing to participate and wouldn’t be missing important class work would be more difficult and time consuming. ]]> 2019-04-17 15:15:56 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352321608 gmnie411 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352323064 Replication 

This study could be replicated in the future with a different group of students or the same students by putting them in a different class setting. The study could be replicated with students from different grades and more students overall too. There was such a small number of students to begin with so replication is most likely necessary. Replication helps add confidence in the results that were originally found. ]]> 2019-04-17 15:19:27 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352323064 mbab034 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352469770 2019-04-18 02:32:50 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352469770 mbab034 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352472504 Statistical significance 

According to the data, the sample size was not big enough to show a considerable outcome. A bigger sample size would make the experiment more effective, however there was a major significance in the 85F treatment. The subjects achieved a much lower score because it was too hot in the room.]]> 2019-04-18 02:56:43 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352472504 mbab034 https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352476363 Results 

We will focus on replicating the experiment into many different location with a bigger sample size in the future. Our first results showed that subjects has a much harder time achieving an a over average score in the 85F treatment room because it was way too hot and the subjects couldn’t think, and focus comfortably.]]> 2019-04-18 03:28:21 UTC https://padlet.com/gmnie411/xgvzidc2jbt7/wish/352476363
