1. A student thinks a special candy will make students smarter and more alert so they never miss an

assignment. To test this idea, she invites friends in her Biology class to help her out and splits the group in

half. All students are asked to complete the same work daily, to eat the same food at meals, and to not

exercise at all (shame, shame). One group is given the special candy once a day at 7am, and the other group

does not get the special candy. After one week , the data shows students that did not receive the candy

turned in more work.

1. Control Group:

2. Variable Group:

3. Dependent Variable:

4. Independent Variable:

5. Her hypothesis:

6. What should her conclusion be?


2. Mrs. Stroberg wants to make sure every student passes Biology. She thinks that is she pays some

students that they will study more for tests and quizzes and get higher scores. So she decides to pay half the

students $20 a week to put in more time to study for any test or quiz. After a month, she looks at all the test

and quiz scores and notices that the average score on every test and quiz are the same in both groups. (Mrs.

Stroberg is very happy with this.)

3. A student thinks that a certain goo will make his hair look awesome. He decides to put the goo on the front

part of his hair but to leave the back alone to see if the awesomeness is better in the front. He uses the goo

for 3 days and goes to the mall to show it off. The student keeps track of every time someone tells him how

awesome the front of his hair is compared to how many times people comment on the awesomeness of the

back part of his hair. He counts the tally marks at the end of 3 days and counts 257 marks for the front being

awesome, and 11 for the back.
