A Scientific experiment is a type of experiment which must be designed to test hypothesis.
The experiments performed by the coach contained three types of variables. These are as follows:
The scientific experiment can be categorized into two samples: the experimental group in which the dependent variable is tested and the control group in which the dependent variable is not present.
However, from the above in the question,
1. The independent variable is the amount of water which was changed throughout the experiment.
2. The dependent variable is the endurance power measured.
3. The hypothesis is If more water is consumed, then more endurance is observed in athletes.
4. The control group is: No control group was included in the experiment.
5. The experimental group is the groups who drank water before practice
6. The constant is the number of players and water consumed per week.
7. The problem is that it lacked the reference group or control group which will provide the data to compare with.
So therefore, a scientific experiment is designed in such a way that it should test the hypothesis.
Complete question:
Coach Damien notices that some of his football players drink more water than others before Friday night games. He is interested if the amount of water the students drink affects their endurance. One week before practice he has each student drink an bottle of water throughout the day. That afternoon, the run the bleachers and he records how many times each player can go up and back before stopping to catch their breath. The next week they do the same thing but drink 2 bottles of water beforehand. The this week they run the bleachers but drink a gallon of water beforehand.
