Answer:
a.) Independent Variable: # of candy bars promised to each group
[ The Independent Varaiable is what you change in the experiment]
b.) Dependent Variable: Quiz Scores
[ The Dependent Variable is what you're testing in the experiment; what the experiment should affect]
c.) Constant(s): Same Quiz, same number of gender kids in each group, same age kids in each group, same ability, and same background. [and same time, I'm assuming.]
[Constants are what you keep the same in the experiment; what you're not changing.]
d.) Testable Question: Will promising kids candy make them do better on tests and quizzes? [or something along this lines of this]
[The Testable Question is what you're trying to find out in the experiment]
e.) Hypothesis: The more candy the students were promised, the better results Mrs. DeFord would get from them.
[The Hypothesis is what the person performing the experiment expects will happen; an educated guess]
f. Formal Conclusion: Data shows that kids who were promised more candy had a better average than kids who were promised less candy/none. Mrs. DeFord's hypothesis was correct, since she assumed the more candy the students were promised, the better they would do on the quiz.
[The Formal Conclusion is what you have learned from the experiment, and wether or not the hypothesis was correct or not.]
I hope this helps! :)
