Abstract: This article suggests criteria for suitable research designs for use with large data bases. The advantages and disadvantages of several types of quasi-experimental designs are compared. Among the more interesting designs are those trying to minimize the possibilities for selection differences between treatment and control groups by considering assignment to treatment in creative ways. When the probability of receiving a treatment is largely outside an individual's control, possible selection bias should be reduced. These designs often use data on populations rather than on the particular recipients of an intervention. Such analysis of impact on a population, rather than of effect on recipients, makes it comparatively difficult to find that an intervention makes a difference. Examples are taken from our research with the Manitoba Health Services Commission data.
