Experimental Research Strategy — Variables, Control, and Establishing Causation | Chapter 7 of Research Methods for the Behavioral Sciences
Experimental Research Strategy — Variables, Control, and Establishing Causation | Chapter 7 of Research Methods for the Behavioral Sciences Chapter 7 of Research Methods for the Behavioral Sciences focuses on the experimental research strategy , the only method capable of demonstrating clear cause-and-effect relationships. By manipulating variables under controlled conditions, experiments allow researchers to rule out alternative explanations and strengthen internal validity. This chapter explains the defining characteristics of experiments, the importance of independent and dependent variables, and the techniques researchers use to control extraneous influences.

Defining Features of True Experiments Experiments are built on four essential elements: Manipulation: The researcher changes at least one independent variable. Measurement: The dependent vari...
