This course is part of the Interaction Design Specialization (www.coursera.o...) led by Scott Klemmer of UC San Diego. In this specialization, you will learn how to design technologies that bring people joy, rather than frustration. You'll learn techniques for rapidly prototyping and evaluating interfaces; how to use these designs to get feedback from other stakeholders; how to conduct fieldwork unearth design ideas; principles of visual design; and how to perform and analyze experiments.

One question about three-way interaction terms. Let's label each variable A(main variable), B(1st moderator), C (2nd moderator). I'm interested in (hypothesize) the relationships A-B and A-B-C. Should all two-way (AB, AC, BC) and three-way interaction terms (A * B * C) be included in a regression model and result or would be it fine to include some of interest (AB, ABC) only?
