Threats to Internal Validity

The material covered in Week 13 is likely new to most students in this course. I have tried my best to provide multiple examples of these concepts, though I recognize that they are difficult to understand when you are first learning them. One thing that I think will be helpful is providing your classmates with additional examples of these concepts that were not used in the textbook or PowerPoint. Thus, for this weeks Discussion post, I will be emailing each of you a concept that I would like you to describe in your post, using a NEW example of the concept.

For example, if I email you the concept of Testing Threats to Internal Validity, it would be your job to create a new, brief example of an experiment in which testing threats may occur. Please post your Discussion post by Sunday, 04/19/2020 at 11:59PM.
