Question 1201422
.


I posted this request to GOOGLE


<pre>
    whether to use sample standard deviation or population standard deviation
</pre>


Below is what GOOGLE answered me


<pre>
    The population standard deviation is relevant where the numbers that you have in hand 
    are the entire population, and the sample standard deviation is relevant 
    where the numbers are a sample of a much larger population.
</pre>

The source is THIS

Probably, it is not 100% rectified answer, which you would want to get,
but it is what is really possible to get.
