Inferential statistics tell us that as long as we are prepared to accept a known level of uncertainty in our projections, ______.

A) we do not need huge sample sizes
B) we do need huge sample sizes
C) sample size is irrelevant
D) we can use any sampling method

Inferential statistics rely on probability and estimation to make projections about a larger population based on a smaller sample. As such, there is always a level of uncertainty associated with these projections, which is typically expressed through confidence intervals or p-values. However, by setting a predetermined level of uncertainty (e.g., a 95% confidence interval), we can use inferential statistics to make reasonably accurate projections even with smaller sample sizes. Therefore, choice A is the best answer.
