Sample mean = x = ( Σ xi ) / n Sample standard deviation = s = sqrt [ Σ ( xi - x )2 / ( n - 1 ) Note that some textbooks use a minimum of 15 instead of 10.The mean of the distribution of sample proportions is equal to the population proportion (\(p\)). http://jamisonsoftware.com/standard-error/formula-convert-standard-error-standard-deviation.php Ability to save and export citations.

The standard deviation of the distribution of sample proportions is symbolized by \(SE(\widehat{p})\) and equals \( \sqrt{\frac {p(1-p)}{n}}\); this is known as thestandard error of \(\widehat{p}\). Test Statistic Calculator Easy! Unlimited access to purchased articles.
