Test developers typically aim to select a representative sample as a good faith effort to ensure that the norm group reflects the broader population to which the test will be applied. This approach helps in making the test results more generalizable and applicable across different segments of the population. Pure random sampling or strict diversified random sampling strategies, while ideal in theory, are often not practical due to logistical, financial, or accessibility constraints. Opportunistic sampling, on the other hand, may not always yield a representative sample.
