What are research variables?

Research variables refer to characteristics or conditions that can change and potentially affect the outcomes of a study. These variables are integral to research design because they allow researchers to isolate, control, and analyze the relationship between different elements within a study. By manipulating or measuring these variables, researchers can identify patterns, make comparisons, and draw conclusions about the phenomena being investigated.

Variables can be classified into different types, such as independent variables (which are manipulated to observe their effect on dependent variables) and dependent variables (which are observed and measured to see how they are affected by the independent variables). Understanding and correctly identifying variables is crucial in research as they influence how data is collected, analyzed, and interpreted, ultimately impacting the validity and reliability of the research findings. This critical aspect differentiates research from mere observation or anecdotal evidence, providing a framework for systematic inquiry.
