# Ch 12: Experimental Design

Use these video lessons to learn about types of experiment design as well as issues you may encounter in creating experiments. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these research design topics.

## Experimental Design - Chapter Summary and Learning Objectives

In this chapter, you'll learn about experimental design, one of the most important factors in scientific research. Instructors explain key aspects of experiment design, including how to achieve random assignment, what purpose control groups serve and why variables matter. This chapter is designed to teach you about topics including:

• Between-subjects designs
• The importance of random assignments
• Group designs, including two-group and matched group design
• Types of within-subjects designs

Video Objective
Between-Subjects Designs: Definition and Examples Define and discuss this type of design that tests two or more groups at the same time.
Random Assignment in Research: Definition and Importance Define and discuss random assignment, its importance and how it is accomplished.
What is a Control Group? - Definition and Use in Research Define and discuss control groups and the use of experimental groups and control groups in research designs.
Two-Group Experimental Designs: Definition and Examples Define and discuss the basic two-group experimental design in psychology research.
Matched Group Design: Definition and Examples Define and discuss matched group design and how it can test for extraneous variables.
Multiple Group Design: Definition and Examples Define and discuss multiple group design and the observation of an independent variable.
What is Factorial Design? - Definition and Examples Define and discuss factorial design and how researchers can study more than one independent variable at a time.
Factorial Design Variations Explain the different factorial designs and how researchers would use them.
Within-Subjects Designs: Definition, Types and Examples Define and discuss within-subjects designs, including one independent variable, multiple independent variables and mixed designs.
Carryover Effects and How They Can Be Controlled Through Counterbalancing Define and discuss carryover effects and how to control them.
