WebFeb 6, 2024 · The variance is a numerical value used to indicate how widely individuals in a group vary. If individual observations vary greatly from the group mean, the variance is big; and vice versa. In short, Variance measures how far a data set is spread out. A value of zero means that there is no variability; All the numbers in the data set are the same. WebDec 2, 2015 · Step 5 - Finally, we'll find the variance. (Make sure to -1 from the sample size.) #s^2 = (21.2)/(5-1)# #s^2 = 5.3# An extra, if you'd care to expand - from this point, if you take the square root of the variance, you'll get the standard deviation (a measure of how spread out your terms are from the mean). I hope this helps.
