Original sentence: Therefore, the above has a population standard deviation of 2.138
Edited sentence: If our 8 values are obtained by random sampling from some parent population, we might prefer to compute the sample standard deviation using a denominator of 7 instead of 8.Note that if the above data set represented only a sample from a greater population, a modified standard deviation would be calculated (explained below) to estimate the population standard deviation, which would give 6.93 for this example.Note that we are assuming that we are dealing with a complete population.See below for an explanation.So, the standard deviation of the set is 6.Step 5: take the non-negative square root of the quotient (converting squared units back to regular units),.Therefore, the above has a population standard deviation of 2.This example also shows that, in general, the standard deviation is different from the mean absolute deviation (which is 5 in this example)
