Charles · Answer 1

b. variability of the estimates made from the data collected in the poll

Explanation:

A sample size tends to influence the precision of the estimates and power of the study. With the increase in the sample size of an opinion poll there is a decrease in the means of the standard deviation. This results in the reduction of the variability of the estimates which is made from the data collected in the poll. Large samples will have small margin of error.
