    Regression, on the other hand, does not compare groups and is not trying to determine if group A is different from group B. Instead, regression looks at the participants all together as one group, examining how the their characteristics predict the dependent variable. For example, if a participant is female and older, they are more likely to have a higher BMI than a younger male. In this case, the regression analysis is looking at ...
