Does chewing gum allow for people to focus more on their work?

# data[].attributes.body
50 people were assigned to chew Wrigley's Extra Long Lasting Flavor Gum TM while they were doing some of the activities we had set aside for them to complete. A different group of 50 people were told not to chew gum or anything else while doing any of their work.

# data[].attributes.body
My selection method was volunteer sampling. People signed up to be part of the experiment, however, the way that they were assigned chewing vs. not chewing was through a random generator.

I video called with all of the people who were chewing gum at one time, we went over when to put the gum in their mouths and the activity at which they were doing. I them had them answer a series of questions and problems to see how ling it took them, and with what accuracy. I did the same thing with the people who didn't chew gum.

Chewing gum makes you focus more on the task you're completing.

# data[].attributes.body
I will see how they performed on the questions and problems that they were told to solve.

I made sure to randomize which people went into which group using a random name generator to separate them. Some lurking variables however would be, age. The age of the person could be a factor in determining how well they performed on the tasks. To try to prevent this, I made sure all participants were ages 17-25.

The control group for this experiment would be the group of people not chewing gum.

My participants will not be blind during this experiment, because they know that they either have gum, or they don't. There is also not double-blind because I had to assign the groups.

This is a crossover experiment because all participants will be going through the same questioning and testing.

# data[].attributes.body
All of the participants volunteered for the study, so I did not have to pay them anything. 50 of them did however need to buy or borrow at least one stick of gum for the experiment. The average small pack of the Extra gum costs $1.35.
50 x 1.35 = 67.50

I am running the experiment with 100 people, so the margin of error would be 10%. That is a very good margin of error because it is low.

# data[].attributes.body
This experiment could be very easily replicated. I would consider adding another day of testing with an entirely different group of people for a lower margin of error. You could also add more questions or puzzles that the participant has to do. Maybe even try a different subject of questioning, other than the math and vocabulary questions given.

# data[].attributes.body
The results show that the subjects with gum did significantly better on the math questions, but not really on the vocabulary questions.

# data[].attributes.body
When doing a subject like math, the results show that chewing gum may be able to help you focus and do better on those questions.

The experiment was redone, and the results were confirmed. When doing math, chewing gum can help you focus and get your work done more efficiently.
