After collecting data from all of the groups, I took the average of all of their results.
Diana
A-30.7
B-31.2
C-26.8
Erick
A-41.2
B-28.6
C-34.4
Sylvia
A-36.9
B-32.8
C-42
Ivana
A-29.4
B-35
C-30.2
Sarah
A-37.2
B-29.5
C-35.9
Jessica
A-12.6
B-15
C-17.1
Angela
A-16.2
B-28
C-21.4
Claudia
A-37.2
B-52.8
C-37.2
Ana
A-37.8
B-40.2
C-45.6
Then I noticed that all of Jessica's averages as well as Angela's A and Claudia's B were outliers from the rest so I decided to remove them from the total average so that it will not manipulate the results.
A-35.533
B-32.883
C-34.866
In conclusion,
A- Stimulant
B- Depressant
C- Regular Water
