Stratified random sampling is the most appropriate method for selecting a standardization group for an achievement test because it ensures that the sample accurately reflects the population's diversity. By dividing the population into strata (or groups) based on characteristics relevant to the test (such as age, grade level, or socioeconomic status), and then randomly selecting participants from each stratum, the resulting sample is more likely to be representative of the entire population. This method helps in achieving a balanced representation of different subgroups within the population, which is crucial for the validity and reliability of the test results.
