What are the types of variables in research methodology?

In research methodology, there are primarily three types of variables: independent variables, dependent variables, and control variables. Independent variables are manipulated or controlled by the researcher to determine their impact on the dependent variable. They are the presumed cause in an experiment. Dependent variables are the outcome or response variable that is affected by the independent variable. They are the effects that are being measured or observed in an experiment. Control variables are the factors that are held constant or controlled to minimize their influence on the relationship between the independent and dependent variables. They help ensure that any observed effects are solely due to the independent variable. Understanding the different types of variables is crucial for designing and conducting rigorous and valid research studies.
