Single proportion
This spreadsheet computes a confidence interval for the estimate of a single proportion.
You are encouraged to try various "what-if" scenarios to examine how the location and width of this confidence interval change when you vary the size of the proportion, the sample size, and/or the confidence level.
The formula used in this spreadsheet is found on page 171 of Rosner (1990) Fundamentals of Biostatistics, Third Edition. Belmont CA: Duxbury Press, Inc. Please consult with a professional statistician before using the output from this spreadsheet in a protocol or publication.
