In research, you have discovered that your data may be compromised. You have been relying on your colleagues to submit actual reading test scores from their classes after administering a new reading program. As it turns out, some of the reading teachers in your district decided not to use the new reading program and are submitting reading test scores after using their “tried-and-true” teaching methods. This information has come to you through a third-party source and you have no way of knowing which data is not reliable. Using the information learned about statistics, what can you do to rectify this situation?
