In correlational research the researcher randomly selects subjects from a population and collects information from them on two or more bits of information. The researcher then calculates a correlation coefficient, which is a statistic that describes how the two variables are related (Runyon, Coleman, & Pittenger, 2000). One advantage of correlational research is that it is economical and fast. Large amounts of data can be compared quickly and cheaply, e.g. by using a questionnaire to collect data. Correlations also allow us to study links between variables that could not be studied in any other way. We could not inflict so much stress on a person that we endanger their life. However, we can use a correlational analysis to show a ...
