on October 8, 2011 | Leave a comment This post covers the 3 applications of standard error required for the MFPH Part A; mean, proportions and differences between proportions (and https://beanaroundtheworld.wordpress.com/2011/10/08/statistical-methods-standard-error-and-confidence-intervals/ their corresponding confidence intervals)… a) What is the etandard error (SE) of a mean? The SE measures the amount of variability in the sample mean. It indicated how closely the population mean is likely to be estimated by the sample mean. (NB: this is different from Standard Deviation (SD) which measures the amount of variability in the population. SE incorporates SD to assess the confidence interval difference beetween sample and population measurements due to sampling variation) Calculation of SE for mean = SD / sqrt(n) …so the sample mean and its SE provide a range of likely values for the true population mean. How can you calculate the Confidence Interval (CI) for a mean? Assuming a normal distribution, we can state that 95% of the sample mean would lie difference between confidence within 1.96 SEs above or below the population mean, since 1.96 is the 2-sides 5% point of the standard normal distribution. Calculation of CI for mean = (mean + (1.96 x SE)) to (mean - (1.96 x SE)) b) What is the SE and of a proportion? SE for a proprotion(p) = sqrt [(p (1 - p)) / n] 95% CI = sample value +/- (1.96 x SE) c) What is the SE of a difference in proportions? SE for two proportions(p) = sqrt [(SE of p1) + (SE of p2)] 95% CI = sample value +/- (1.96 x SE) Share this:TwitterFacebookLike this:Like Loading...
