Step 6// Making it a secret

We kept the control group and test groups separate so that neither would know what the other group was doing, therefore making our trial more valid.

We decided not to disclose to the participants what we would be testing them on exactly so that they could not go home, google the answers, and then ace the pretest. As we had to sessions, we made sure that we did not let the people who had taken the test first go back to their classroom and tell their classmates what the test was going to be on and the answers to the test as this would ruin our study completely.
