PSYB01H3 Chapter Notes - Chapter 8: Dependent And Independent Variables, Inflectional Phrase, Internal Validity
Document Summary
Ability to identify cause-and-effect relations btn variables: we can infer that one variable actually creates/enacts a change in another variable covariation: when changes in one variable are associated w changes in another variable. Part of determining causality this demonstrates that two variables vary/change together in a systematic way: covariation along cannot establish causality. Mundane realism: the degree to which a study parallels everyday situations in the real world. How closely the study parallels w the real world two-group design: an experimental design that compares two groups or conditions and is the most basic way to establish cause and effect. Experimental group: the group/condition that gets the key treatment in an experiment. Control group: any condition that serves as the comparison group in an experiment. Experimental control: keeping everything btn groups the same except for one element you want to test (manipulate) in an experiment. Experimental hypothesis: a clear and specific prediction of how the iv will infl the.
