Study Notes
Variables in Research
- Variable Definition: Object or concept that can vary or change, essential in research for analyzing relationships and impacts.
Types of Variables
- Quantitative Variable: Represents data in terms of amount, measured with numerical units (e.g., height, weight, temperature).
- Qualitative Variable: Represents data in terms of groups, encompassing rankings, classifications, and binary outcomes (e.g., gender, type of pet, satisfaction level).
Independent Variables
- Independent Variable: The factor that is manipulated or controlled in an experiment to test its effects on the dependent variable. It stands alone and isn't changed by other variables in the study.
Dependent Variables
- Dependent Variable: The outcome or response measured in an experiment, which is expected to change when the independent variable is altered. It depends on the influence of the independent variable.
