Experimental Design
Athabasca University
This tutorial is a component of the courseware of the Psychology Center of Athabasca University. Some technical notes provide information about the instructional-design principles on which the tutorial is based. In Part 1 of this tutorial, you will be introduced to nine sources of threat to internal validity. In Part 2, you will be asked to classify 36 hypothetical experiments as internally valid or not. If not, you must select the threat to internal validity from one of the nine sources introduced in Part 1. Great for students.
