All of the options (sampling method, sample size, and variability in the population) can influence how well a statistic estimates a parameter. The sampling method affects whether the sample is representative of the population, the sample size affects the precision of the estimate, and the variability in the population affects the amount of error in the estimate. Therefore, all three factors impact how accurately the statistic can estimate the population parameter.
