Outcome-
Our study has been viewed by thousands of people and is now one of the most popular fruits in the grocery store. It is now also very common to see students eating lemons before a test.

Statistical significance-
Our data is statistical significant because of the 5% difference between the average score of the lemon and the orange. There was a 7% difference between the lemon and the group who had nothing which proves eating a lemon before a math test will increase your score.

Results-
In the end of the experiment, the group who received lemons before the test had a higher average schore then the groups who had oranges or nothing. The group with the lemons had an average score of 87%. The group with the oranges had a score of 83% and the group who had nothing scored an average score of 80%.

Sample/MOE-
We are testing on 27 highschool students and our margin of error is at 19.2. This is pretty high so it will require this experiment to be done a few times to get the persice results. After this experiment has been done a few times, I should be a good representation of the whole population.

Blind/Double blind-
We were able to create a bold study because we put each group in a separate room and gave them the fruit they were assigned. Then they all took the tes not knowing that other groups ate a different fruit. We would not be able to do a double blind because then the distributer would know that he is handing out different fruit.

Randomized/Lurking Vairable-
We told the teacher to select 27 random kids in their class. Then we used a calculator to generate random numbers to put kids into groups. The lurking Variable is every kid has a different skill level and my understand the material better. Another lurking Variable is the teacher my have given us the top 27 kids in the class.

Matched pair design-
We matched kids together with the same skill level and the kids who had the same teacher. We matched the kids prior to the study

Control group-
The control group was the group who will receive no fruit so we can compare the results with them.

Replication-
We will replicate the same experiment on kids from a different math class or kids from another school to ensure that our results are correct.

Selection method-
The students were picked from the local highschool who all take the same math class.

Response Variable-
After the math test, the students who ate a lemon before the test scored higher than the students who had nothing or an orange. The students who ate the lemon first had an average test score of 87%. The kids who had an orange before the test had an average score of 83%. The kids who had nothing scored an average of 80%.

Explanatory Variable-
The explanatory variable was which fruit the groups would receive whether it be with or without a fruit.

# data[].attributes.body
Treatments-
Before the test each group will be given a different fruit. One group will receive a orange, another group will be given a lemon, and the last group will receive no fruit.

Experimental Units-
27 students are randomly divided into 3 separate groups which gives a total of 9 individuals per group

Question-
Does eating a lemon or an orange before a test affect test scores?
