Histograms showing the mean and the range (Image by author) Notice that most of the values are concentrated around 15,000 and 35,000, but there is an extreme value (an outlier) of 200,000 that pushes up the mean to 40,500 and dilates the range to 185,000. Now, going back to the concept introduced earlier, let’s calculate the variance.
WebbThe standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly … WebbExample: One Standard Deviation Below The Mean. Given a normal distribution with a mean of M = 100 and a standard deviation of S = 15, we calculate a value of M – S = 100 – 15 = 85 is one standard deviation below the mean. So, a value of 115 is the 84.1 st percentile for this particular normal distribution. This corresponds to a z-score of ...
