EXPERIMENTS AND EXPERIMENTAL DESIGN

EXPERIMENTS AND EXPERIMENTAL DESIGN. ETHICAL ISSUES IN RESEARCH. Logic of causality. If X, then Y and If not X, then not Y Or, colloquially: If the stimulus is given, then the outcome occurs and If the stimulus is not given, then the outcome does not occur.

Experimental design 2:

Experimental design 2:. Good experimental designs have high internal validity: To unequivocally establish causality, we need to ensure that groups in our study differ systematically only on our intended independent variable(s) and not on other confounding variables as well.
