Possible lurking variables would be gender,grade, and best class. Students would be blocked by grade , then by gender. Students would then be randomly selected then grouped by best class.

# data[].attributes.body
The control group will have no water befor or during the test, to see if having water affects scores(no treatment)

# data[].attributes.body
Not possible because one group knows they won’t be getting water at all and the rest of the groups are getting a treatment

# data[].attributes.body
Students with similar best class will be grouped to take their test in that class with different treatments

# data[].attributes.body
320 students, 80 in each group (4 in total ), 5.6% more the results may deviate by roughly 5.6% from the average

# data[].attributes.body
Randomly select 320 more students, blocked and grouped the same way with same treatment

Seeing a student who drank more water generally older better than who drank less the results would be statistically si
