WebTaking the square root solves the problem. The standard deviation measures the spread in the same units as the data. Notice that instead of dividing by n = 20, the calculation divided by n – 1 = 20 – 1 = 19 because the data is a sample. For the sample variance, we divide by the sample size minus one ( n – 1). WebMean deviation is the arithmetic mean of the absolute deviations of the observations from a measure of central tendency. If x 1, x 2, … , x n are the set of observation, then the mean deviation of x about the average A (mean, median, or mode) is Mean deviation from average A = 1⁄n [∑ i x i – A ] For a grouped frequency, it is calculated as:
