Types of Variables: Dependent, Independent, Moderating, Mediating & Control Variable
Updated: November 19, 2024
Summary
Variables in research studies can be categorized into dependent, independent, moderating, mediating, and control variables. The dependent variable is influenced by the independent variables, while the independent variable predicts changes in the dependent variable. Moderating variables have a conditional effect on the relationship, while mediating variables explain the causal relationship between variables. Control variables are important for ensuring observed effects are due to studied variables and not external factors. Understanding these types is crucial for accurately interpreting regression results and comprehending variable relationships in a study.
Types of Variables
Variables can be categorized into dependent, independent, moderating, mediating, and control variables. Understanding these types is essential for interpreting regression results accurately and understanding the relationships between variables in a study.
Dependent Variable
The dependent variable is the criterion or response variable that is influenced by the values of independent variables. Changes in independent variables lead to changes in the dependent variable.
Independent Variable
The independent variable is the predictor variable that may impact the dependent variable. It is also known as the explanatory variable and is used to explain and predict changes in the dependent variable.
Moderating Variable
A moderating variable has a conditional effect on the relationship between the independent and dependent variables. It influences the strength and direction of the association between these variables based on its values.
Mediating Variable
A mediating variable lies between the independent and dependent variables, explaining the causal relationship between them. It helps clarify the underlying mechanism through which the independent variable affects the dependent variable.
Control Variable
Control variables are included in research studies to mitigate the risk of wrongly attributing explanatory power to independent variables. They help ensure that the observed effects are due to the studied variables and not external factors.
FAQ
Q: What is a dependent variable?
