Calculation of CI for mean = (mean + (1.96 x SE)) to (mean – (1.96 x SE)) In practice the finite population correction is usually only used if a sample comprises more than about 5-10% of the population. Even then it may not be applied if researchers wish to invoke the superpopulation concept', and apply their results to a larger, ill-defined, population. When several random samples are extracted from a population, the standard error of the mean is essentially the standard deviation of different sample means from the population mean. However, multiple samples may not always be available to the statistician. Fortunately, the standard error of the mean can be calculated from a single sample itself. 2013-01-29 · A cluster randomised double blind controlled trial investigated the effects of micronutrient supplements during pregnancy.

In equation(4), represent the calculate standard deviation, is the size of the population, means the mean of population and represents the value of each point of Standard Error of the Mean (SEM) The standard error of the mean also called the standard deviation of mean, is represented as the standard deviation of the measure of the sample mean of the population. It is abbreviated as SEM. For example, normally, the estimator of the population mean is the sample mean. 2018-02-03 · Definition of Standard Deviation.
