Study Notes
Variables
- Represents events, situations, behaviors, or characteristics with varying values.
Categories of Variables
- Two main types: Conceptual Variables and Operational Variables.
Conceptual Variables
- Abstract ideas forming the foundation of research hypotheses.
- Not directly measurable; examples include self-esteem, intelligence, anxiety, and aggression.
Operationalism
- Scientific concepts must connect to observable or measurable events.
- Conceptual variables are translated into measurable operational variables.
Operational Variables
- Definitions of abstract concepts used for measurement or manipulation in research.
- Examples include IQ tests and heart rate measurements.
Reliability and Validity
- Essential characteristics of effective operational variables.
Reliability
- Ensures consistent measurement of the same conceptual variable across different instances.
Validity
- Reflects the accuracy of the operational variable in measuring the intended conceptual variable.
Independent Variables (IV)
- Presumed to cause changes in other variables.
- Researchers manipulate IV to observe its effects on behavior, requiring at least two levels.
Levels of Independent Variable
- Studying alone: Level 1.
- Studying with one person: Level 2.
- Studying in a group: Level 3.
Dependent Variables (DV)
- Changes in response to the independent variable.
- Always measured to assess the effects of the IV.
