While you now know how to find correlation coefficient in each of the groups, but still we do not know if the difference in relationship between groups is significant. Gawra cares about the quality and consistency of her products. Perhaps the most common scenario for computing difference scores is where youve got a pre-test/post-test scenario, and you want to see how the dependent variable has changed between the two conditions (difference scores are sometimes termed change scores). the best step is to specify one is looking for a reference, so that it can be found the right test tools and appropriate, There is no clear guidanc group contains cases with missing gender values and nonmissing height values.
