Those costs may never be offset by consumer sales if the product or idea never makes it to market. Learning how to conduct an experiment is important to understanding how psychologists prove and disprove theories in this field. 3 Advantages of Correlation Research Correlational research allows researchers to collect much more data than experiments. These experiments can also be easier for other researchers to replicate. An example is Milgrams experiment on obedience or Loftus and Palmer's car crash study. Correlational Study Advantages and Disadvantages The third variable problem or a confounding factor exists when a third variable that is not being measured Obtaining a significant correlation between two variables never guarantee the possibility of the existence of the other one.
