If people who normally wear glasses are given contacts, will their reading comprehension improve?]]> 2019-04-16 15:03:27 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352001062 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352002186 Experimental units 

100 randomly selected people at BCHS who wear glasses.]]> 2019-04-16 15:06:08 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352002186 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352007022 Selection method

We will have 100 students with glasses volunteer and assign each person a number 1-100 and SRS 50 people randomly to take a reading test. ]]> 2019-04-16 15:16:56 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352007022 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352007372 Blind

We cannot make this experiment blind because people will know who is wearing glasses or contacts. ]]> 2019-04-16 15:17:50 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352007372 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352009044 Background 

Glasses and contacts can give different looks on life, so we wanted to see if this effects a different look on testing. Reading comprehension was a perfect test to take because you really have to look for key words or phrases and what if the different views changes that. ]]> 2019-04-16 15:22:04 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352009044 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352009445 Control group

The control group would be the people who still wear their glasses rather than changing them to contacts. ]]> 2019-04-16 15:23:01 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352009445 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352010096 Sample size/ MOE

Our sample size is 50 people and our margin of error is 14%]]> 2019-04-16 15:24:35 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352010096 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352034129 2019-04-16 16:26:05 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352034129 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352034696 Replication 

We did the same test thefollowing  year with 50 other volunteers with glasses to see if we could get better results. ]]> 2019-04-16 16:27:35 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352034696 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352035246 Explanatory variable 

Testing with contacts.]]> 2019-04-16 16:29:03 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352035246 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054252 Treatments

Treatments in this case would be glasses or contacts. ]]> 2019-04-16 17:18:42 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054252 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054784 Crossover 

We will split the students in half randomly and then later will have them switch to whichever eyewear they havent taken the test with yet. ]]> 2019-04-16 17:19:55 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054784 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054867 2019-04-16 17:20:08 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352054867 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352055653 Outcome 

We found that people with glasses did an average of 2% worse that the ones who worse contacts. It was believed that the glasses were more of a distraction to the students. ]]> 2019-04-16 17:21:54 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352055653 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352056530 Statistical significance 

We randomly chose 50 people out of 100 volunteers to take a reading comprehension test. Half of the students were assigned to wear glasses and the other half contacts to see how they would perform on the test. The results did not have a significant enough different to give a statistical analysis.]]> 2019-04-16 17:24:02 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352056530 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352058430 Expenses

The expenses for giving each student a pair of contacts for their prescription was around $2,000. To rent the location where it was held was $300 and the tests were $150 for all of them together. We also gave $100 to the top scoring student. In total the cost was around $2,550.]]> 2019-04-16 17:28:35 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352058430 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352059057 Results 

Based on the data taking the test with glasses gave an average score of 78% and taking a test with contacts gave an average score of 81%.]]> 2019-04-16 17:30:21 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352059057 cozam280 https://padlet.com/cozam280/yuze6xwmbd0h/wish/352183191 2019-04-17 02:53:41 UTC https://padlet.com/cozam280/yuze6xwmbd0h/wish/352183191
