If 'standard deviation of population' and 'standard deviation of sample means' were to be computed by hand, what is the difference in the formula?

The population standard deviation (often represented by the Greek letter sigma) is measures the variability of data in a population. It is usually an unknown constant.
The sample standard deviation (usually represented by S) measures the variability of data in a sample. It is easy to compute (compared to a population standard deviation) because it is based on a small and manageable sample.
