The 1992 Election... Mathematics?
Author: Floyd Vest
When reporting the results of a survey, the organization usually gives the sample percentage as an estimate of the actual population percentage, and announces the margin of error. They may not give the sample size and the confidence level. How is the margin or error calculated? Surprisingly, the formula is simple and involves only the sample size, the margin of error, and the confidence level.
