In our second calculation, we will treat our data as if it is a sample and not the entire population. We divide by one less than the number of data points. So, in this case, we divide by four. This means that the sample variance is 30/4 = 7.5. The sample standard deviation is the square root of 7.5. This is approximately 2.7386.

Had we used the complete population, we could divide by the actual number of dataset. This correction (dividing by n-1 instead of n) is called Bessel’s correction. Sample and population measurements also use a different set of symbols to indicate them. For example, sample standard deviation is s while population standard deviation is σ (sigma). As we have seen in the examples above, the population could be enormous in size. There could be millions or even billions of individuals in the population.
