Quizplus · Accepted Answer

To determine whether changing one variable causes changes in another variable, we need to conduct experimental research. In an experimental design, the researcher manipulates one variable (the independent variable, in this case education) and measures the changes in another variable (the dependent variable, in this case income). This allows for the establishment of causal relationships between the two variables. Surveys and correlational designs can provide information about how variables are related, but they cannot establish causality. Naturalistic observation involves simply observing behavior in its natural setting and is not suitable for investigating causal relationships between variables.
