Apr 03, 2019 · First, calculate the deviations of each data point from the mean, and square the result of each: variance = = 4. Where μ is Mean, N is the total number of elements or frequency of distribution. Standard Deviation is square root of variance. To take another example, the mean diastolic blood pressure of printers was found to be 88 mmHg and the standard deviation 4.5 mmHg. One of the printers had a diastolic blood pressure of 100 mmHg. The mean plus or minus 1.96 times its standard deviation gives the following two figures: 88 + (1.96 x 4.5) = 96.8 mmHg. 88 – (1.96 x 4.5) = 79.2 mmHg. A sampling distribution is the probability distribution of a sample statistic when samples of size nare taken randomly from the population repeatedly (typically, a simple random sample is used). The sampling distribution of the sample mean has mean and standard deviation denoted by
