Answer
# Brief Explanations:
Bias is related to sampling method, not sample - size. Variability of opinions in the sample is a characteristic of the population and not directly affected by sample size. Non - response effect is about those who don't respond, not sample size. Larger sample size reduces the standard error of estimates, thus reducing the variability of estimates made from the data.
