It was concluded that those who drank coffee got better scores on the tests. This will make students encouraged to drink coffee before tests and cause better education throughout Aerica

*Coffee $2.00 per person a day
*creamers, sugars, etc. $2.00 a day
*team salaries: $10,000
*payment to experimental units: $200 a person

A random sample was more representative of the population. Our study yielded similar results compared to a study done by the CDC who also found that coffee improved test results

# data[].attributes.body
Those who drank coffee before the test got grades between 80-100. Those who didn’t drink coffee before got lower than 80 on their tests

We can block the students by grade level and that’s beneficial since those students  will all be taking the same level tests and have mostly the same level knowledge. We will take 75 students from each grade

We can replicate this study a year later in order to make the study more reliable

With a sample of 300 our margin of error is 5.77%

Having a blind study is not necessarily possible since it will be evident that the subject is drinking coffee because of the smell and color

The control group will be the one who does not drink coffee before school or taking a test

Other things the person may eat/drink might affect the study. It will be randomized by selecting random students walking around around campus
