In this lesson, we are going to be talking about research designs, also known as research strategies. First we will talk about descriptive versus inferential statistics. After that, we are going to talk about variables in relationships. We are going to introduce three different categories of research strategies or designs and then we are going to talk about why cannot other strategies besides the experimental strategy determine causation. We are going to talk about what is so special about experiments. Finally, we are going to end with some experimental terminology.
