Explanation: The variability within the population data is a critical factor in determining the minimum sample size. High variability requires a larger sample size to capture the diversity of the population accurately, reducing the margin of error and increasing confidence in the results. Statistical methods, such as confidence interval calculations and standard error analysis, account for variability to ensure the sample adequately represents the population. Population size has a minimal impact unless it is small, as sampling error depends more on variability and less on population size. Option A: While population size affects the sampling frame, it is not the primary determinant unless the population is small. Option C: Computational resources may limit the sample size but are not a statistical requirement for determining minimum size. Option D: The length of the questionnaire impacts response rates, not the statistical validity of the sample size. Option E: The sampling technique influences how the sample is drawn but does not dictate its size requirements.
