Does paper color affect test results for high school students? I want to figure out if the color of paper given to a student before taking a test, can improve his or her grade?

# data[].attributes.body
Different colors of exam paper: Grey, Blue, Green, and White

# data[].attributes.body
Treatment: Grey vs Blue vs Green vs White test scores

The test results is the explanatory variable because it is what is being tested and the results that we are looking for. It is dependent on the explanatory variable.

The paper color is the explanatory variable because it will be the variable that "effects" the test results

White Paper
*There is no placebo in this experiment because they do not think that they are receiving special treatment

The students are unaware of what the study is for and they believe that they are just taking their tests

The experiment was conducted for psychometric testing purposes to see if there would be an increase in test results by changing the color of the test. This would help students in the future if this was true.

Random Block, the experiment will be set up like this: there are 600 students that are attending paradise valley community college and are taking MAT151 by the three professors. There are 300 students who have an A in the class and are motivated to succeed on their tests. The students are randomly selected and number 1-100 in each class. The students are all assigned a random number done by a generator. Students 1-25 are assigned grey, 26-50 are assigned blue, 51-75 are assigned green, and 76-100 are assigned white. For each exam session, all students receive the same test.

This experiment will be done three times in total, with three different test with the same students

# data[].attributes.body
The sample size is 300 students in total. 100 students randomly selected from 3 different schools that follow the same exact test and guidelines.
The Margin of error is: 5.8%

# data[].attributes.body
This process is repeated three time with the same students but with different exams. In addition, this experiment will be done at three different but similar colleges. The professors will be giving the students the same exact tests.

Depending on the different professors, the students grades could depend on their teaching skills.

# data[].attributes.body
During this experiment, the data displayed does not show any statistical significance or association between the color of paper and test results.

# data[].attributes.body
In the end, there is NO association between paper color and test results. All of the results varied, but with all of them together, they balanced out to about the test grade.
