Document Summary
Cause and effect connection one variable is considered to cause the other variable. Independent variable - considered to be the cause. Dependant variable - considered to be the effect. The independent variable is expected to cause changes in the dependent variable. In an experiment, the manipulated variable is the independent variable and the variable that is. Research focuses primarily on the independent variable with the researcher studying the effect of a single independent variable on numerous behaviours. Other researchers may focus on a specific dependent variable and study how various independent variables affect that one behaviour. Experimental method reduces ambiguity in the interpretation of results, enabling researchers to make. Causal claims about how variables are related to each other. Temporal precedence introducing one variable before the other. Eliminate alternative explanations by controlling the environment except for the independent variable being manipulated. Experimental control - accomplished by treating participants in all groups in the experiment identically.
