For example, itminimizes selection bias and ensures that subgroups within the population receivegenuine representation within the data, but it also includes many conditionsthat must be met in order to be used correctly. Some of the conditions includethat every member of a population must be studied and categorize eachindividual into a subpopulation. Finding an all-inclusive list is just one ofmany problems. Another is correctly categorizing each member of the populationinto a single class.
