Study Notes
Types of Variables in Research
- Qualitative Variable: Consists of non-numerical data such as pictures, words, statements, clothing, written records, or descriptions of situations.
- Categorical Variable: Varies by type or kind, grouping data into distinct categories without a numeric representation.
- Independent Variable: Presumed to cause changes in another variable; often manipulated in experiments to observe effects.
- Dependent Variable: Presumed to be influenced by one or more independent variables; the outcome that researchers measure.
- Mediating Variable: Occurs between two other variables in a causal chain, explaining the relationship between the independent and dependent variables.
- Moderating Variable: Changes or 'moderates' the strength or direction of the relationship between other variables, impacting how the independent variable affects the dependent variable.
- Nominal Variable: Based on non-numerical data similar to qualitative variables, emphasizing classification without a numeric measure.
