Difference between "correlation" and "related".Watch
Despite thoroughly researching both types of experimental design, I am still lost when it comes to applying which one of these to an example experiment. They then both seem to fit the experiments or neither quite fits right. Thanks for the help and sorry if this is a stupid question.
Correlation is objective and relation is subjective. Correlation is the statistical relationship between two variables, whereas saying their related is how you conclude upon that link, i.e. positive/negative correlation means they are related, but no correlations means no relationship.
In psychology, for experimental design problem questions we have been taught that if it is correlation then the scenario will say that they are looking for a test of association or correlation. Whereas if it is relate, the scenario will say that they are looking for a test of difference, related being either matched pairs or repeated measures and unrelated being independent groups. Hope this helps
