Propensity score matching is a technique used in observational studies where individuals in the treatment group are matched with individuals in the control group based on their propensity score, which is the probability of receiving the treatment based on a set of relevant covariates. This technique allows for individuals to be matched on multiple variables to make the groups more comparable. Option A is incorrect because propensity score matching does not use random assignment. Option C is incorrect because propensity score matching does not pertain to studying persons of different ages, and option D is incorrect because extreme scoring is not a criterion for selection in propensity score matching.
