Can the color of someone’s room affect their happiness?

# data[].attributes.body
We found 10,000 high school students that are currently enrolled in schools around Arizona.

# data[].attributes.body
Our explanatory variable were the students with the different colored rooms.

# data[].attributes.body
10,000 students were randomly assigned to spend one day in each colored room. The colors are res, blue, grey, yellow and black.

# data[].attributes.body
With a sample size of 10,000 our margin of error is 1%. This low of a margin of error is good and means that our results should provide a good representation of the population.

# data[].attributes.body
Our control group is the group of 16000 students that spent one day in a white-walled room.

# data[].attributes.body
At the end of 10 days, we analyzed the self reported happiness sheets that are scaled from 1-10.

# data[].attributes.body
Our experimental units were found through our relationship between us and the high schools around Arizona. We then used the cross over design to choose our participants.

# data[].attributes.body
To do a randomized block design we would have to split the participants up by gender and then they would be randomly assigned to a room

# data[].attributes.body
In order to do a Matched Pair Design, we would match them up based on age and gender and then Randomly given a room to spend time in.

# data[].attributes.body
We are not able to double blind our subjects because they participants will know what colored room they are spending time in. We are able to blind them by not allowing the people analyzing their results to not know what color the rooms were.

# data[].attributes.body
The crossover would be the best choice for this experiment because we want each person to be able to experience each room color. They would spend one day in each colored room with one day in-between two diminish any possibility of carry over from the previous room

# data[].attributes.body
At the end of the 12th day, it was understood that the brightest color, yellow, created the most happiness. The Darkest color, black, led to the least amount of happiness.

In order to replicate this study we will take another group of 10,000 people and set up the cross over design to confirm that the results are valid and are significant.
