The aim of correlational research is to identify variables that have some sort of relationship do the extent that a change in one creates some change in the other. Correlational Research When scientists passively observe and measure phenomena it is called correlational research. Here, researchers do not intervene and change behavior, as they do in experiments. In correlational research, the goal is to identify patterns of relationships, but not cause and effect. A correlation between variables indicates that as one variable changes in value, the other variable tends to change in a specific direction.
