interval on the mean when σ is estimated View Multimedia Version When you compute a confidence interval on coefficient of variation confidence interval the mean, you compute the mean of a sample in order to estimate the mean of the population. Clearly, if you already knew the population mean, there would be http://www.healthknowledge.org.uk/e-learning/statistical-methods/practitioners/standard-error-confidence-intervals no need for a confidence interval. However, to explain how confidence intervals are constructed, we are going to work backwards and begin by assuming characteristics of the population. Then we will show how sample data can be used to construct a confidence interval. Assume that the weights of 10-year-old children are normally distributed with a mean of 90 and http://onlinestatbook.com/2/estimation/mean.html a standard deviation of 36. What is the sampling distribution of the mean for a sample size of 9? Recall from the section on the sampling distribution of the mean that the mean of the sampling distribution is μ and the standard error of the mean is For the present example, the sampling distribution of the mean has a mean of 90 and a standard deviation of 36/3 = 12. Note that the standard deviation of a sampling distribution is its standard error. Figure 1 shows this distribution. The shaded area represents the middle 95% of the distribution and stretches from 66.48 to 113.52. These limits were computed by adding and subtracting 1.96 standard deviations to/from the mean of 90 as follows: 90 - (1.96)(12) = 66.48 90 + (1.96)(12) = 113.52 The value of 1.96 is based on the fact that 95% of the area of a normal distribution is within 1.96 standard deviations of the mean; 12 is the standard error of the mean. Figure 1. The sampling distribution of the mea
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 http://cpa.sagepub.com/content/41/8/498.full.pdf 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 standard 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...
