The independent variable is the amount of water consumed by the football players.
The dependent variable is the football players' endurance, measured by how many times they can run up and down the bleachers before catching their breaths.
The coach's hypothesis was that the more water consumed, the more endurance the players will have.
There is not a control group present in this experiment, but it would be the set of players who did not drink a bottle of water before practice.
The experimental group is the set of players who did drink a bottle of water before practice.
The constants in the experiment are the operational definitions of endurance (how he measures their endurance), the amount of water each player drinks throughout the week, and the players used in the experiment.
The lack of a set control group poses a threat to the accuracy of the experiment's results.
The primary ethical guidelines that apply to this experiment are those of human experimentation.
The use of humans as subjects of experimentation would seem to demean their human dignity. The issue of abuse of the human subjects and also the prospects of the clinical trial going wrong (such as causing an adverse effect on the subjects) also raise ethical challenges even when the subjects are volunteers. In case of a clinical error, what is the right compensation?
The answer is option 1, 3, 5,7, and 10
Yeah it haves to be C if not then it could be b I think but I probably more positive with c
