There are a couple of conditions to note when using this formula to calculate margin of error: n x p must equal 10 or more; n x (1-p) must equal 10 or more; Confidence Interval Calculator. I've always been fascinated by numbers and how technology can solve complex problems. We start by setting 1 - $\alpha$ equal to the confidence coefficient. 7/1000) ME = 0. In order to find $ z_{\alpha/2} $ (or $ t_{\alpha/2} $), we must first find the value of $\alpha/2$. Solution : Data given probability p = 0. , because of weighting). 96 x √(0. This is a particular issue when dealing with results that are very close, or contentious, or challenging to the interests and assumptions of the people to whom the data is being presented. 2, the population size is 1029, the sample size is 112, and the confidence interval is 95%. Find out how much the opinions and behavior of the sample you survey is likely to deviate from = sample proportion (“P-hat”), n = sample size, z = z-score. Example 1: Calculate the MOE with FPC if the sample proportion is 0. Learn how to find margin of error and use our accurate online calculator to measure it right away.
