Independent and Dependent Variables in Research
Independent Variables (IVs) are used to investigate how changes in the independent variable influence the dependent variable. The researcher actively changes or controls the independent variable. It represents the presumed cause in a cause-and-effect relationship.
Examples:
- Education Study: Amount of study time (IV) affects test scores (DV).
- Medical Trial: Dosage of a drug (IV) affects patient recovery rates (DV).
- Marketing Research: Type of advertisement (IV) affects consumer purchasing behavior (DV).
Dependent Variables (DVs) To observe and measure the effect of the independent variable. The researcher measures the dependent variable to gather data. It represents the presumed effect in a cause-and-effect relationship.
Examples:
- Education Study: Test scores (DV) are affected by the amount of study time (IV).
- Medical Trial: Patient recovery rates (DV) are affected by the dosage of a drug (IV).
- Marketing Research: Consumer purchasing behavior (DV) is affected by the type of advertisement (IV).
Dependent and Independent Variable
Dependent and Independent Variables are the output and input respectively in an experiment. In an experiment, in contrast, the independent variable in an experiment is something we intentionally manipulate or alter while the dependent variable is what we measure and is dependent upon the modifications we make to the independent variable.
In this article, we will learn what are dependent and independent variables, their definitions, the Graph between Independent and Dependent Variables along with difference between Dependent and Independent variables in Tabular Form.
