PSYB01H3 Chapter Notes - Chapter 4: Operational Definition, Direct Manipulation Interface, Helping Behavior
Document Summary
Variable any event, situation, behavior or individual characteristic that can take more than one value (i. e. , it varies) (pg. A variable must have two or more levels. For some variables, the values will have true numeric, or quantitative, properties. Situational variable describes characteristics of a situation or environment. Response variable refers to the responses or behaviors of individuals. Participant variable describes the characteristics of individuals that they bring with them to a study. Operational definition a definition of the variable in terms of the operations or techniques the researcher uses to measure or manipulate it (pg. Variables must be operationally defined so that they can be studied empirically. Different researchers may operationally define similar variables in different ways, depending on the research questions, resources they have available and their own creativity. Help us to communicate our ideas to others. Researchers must translate variables into specific operations to manipulate or measure them.
