Comparative Trend Research
Comparative trend research is a quantitative non-experimental design that tracks changes in one or more variables over time within two or more distinct groups or populations. By drawing independent cross-sectional samples from each group at multiple time points, it reveals whether trends diverge, converge, or differ in magnitude across groups — answering not just 'is this changing?' but 'is it changing differently for different populations?'
