If you want to know how to compute standard deviation in a PostgreSQL server, then this tutorial is for you

In this PostgreSQL video tutorial, I have started with an introduction to standard deviation. A standard deviation measures the amount of variability in a set of values. Then I explained how to use the STDDEV_POP() function to compute the standard deviation of entire data or column values.
Finally, I explained how to use the STDDEV_SAMP() function to compute the standard deviation of a subset of the entire dataset or column values.

Here are the key topics covered:

STDDEV_POP() function in PostgreSQL
STDDEV_SAMP() function in PostgreSQL
