Podsumowanie	Comparative explanatory research is an observational design that systematically examines two or more groups, nations, organisations, or time points in order to explain why differences in outcomes occur. Rather than merely describing variation, it seeks causal or contributing mechanisms by holding some conditions constant while contrasting others — drawing on Mill's classical methods of agreement and difference.	Survey research is a quantitative (and sometimes mixed-methods) design in which a researcher collects standardised self-report data from a sample drawn from a defined population, using a questionnaire or structured interview. It is the dominant non-experimental strategy for describing population characteristics, estimating prevalence, mapping attitude distributions, and testing bivariate or multivariate associations across social, behavioural, and health sciences.
