The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.". Some factors that affect the width of a confidence interval include: size of the sample, confidence level, and variability within the sample.
