variablecentered

Variable-centered design is a research methodology that focuses on the variables of interest, rather than the participants or the context. This approach is particularly useful in experimental and quasi-experimental designs, where the primary goal is to understand the causal relationships between variables. In variable-centered design, the researcher manipulates one or more independent variables to observe their effects on dependent variables. This method allows for precise control over the variables being studied, making it easier to isolate and identify causal relationships. One of the key advantages of variable-centered design is its ability to provide strong internal validity, as the researcher can directly manipulate the variables of interest and observe their effects. However, this approach may have limitations in terms of external validity, as the findings may not generalize to real-world settings or different populations. Variable-centered design is often used in fields such as psychology, education, and social sciences, where understanding the relationships between variables is crucial for theory development and practical applications.
