Survey uncertainty with a given population proportion was created by milanoleonardo
Hello!
I have to estimate the uncertainty of the result of a survey where there sample size was defined to have an uncertainty of 2.76%, based on p a p value of 0.5.
The 2.76% error is calculated assuming a 50% population proportion, which is a worst case scenario assumption:
size sample 1260
confidence interval 1.96 (95 percent)
proportion: 50.00% error 2.76%
The result of the survey is 4%: with this population proportion what would be the error?:
size sample 1260
confidence interval 1.96 (95 percent)
proportion (p): 4.9% error ????
Thank you!

Volunteers are not paid.
Not because they are worthless, but because they are priceless

Hi, milanoleonardo,
what is your question about the design issues of Limesurvey?
Or do you want us to have a look into a statistic table?

But your question is rather about the results/outcome than the design of an online questionnaire or survey, right?
