Systematically Arrange Independent Variables (B-03)
from A BA Study Podcast Hosted by Hannah Dollinger
In the first episode of really and truly talking about experimental design, I talk about the Fourth Edition Task List item B-03: Systematically arrange independent variables to demonstrate their effects on dependent variables. More specifically, I get into extraneous and confounding variables, plus threats to internal validity (#FUNAF). References: Cooper, J. O., Heron, T. E., & Heward, W. L. (2020).
