https://en.wikipedia.org/wiki/Standard_deviation says
In statistics, the standard deviation (SD, also represented by the Greek letter sigma Ï or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
But technically, our #stdev is only one of several variants, namely 'corrected sample standard deviation' [https://en.wikipedia.org/wiki/Standard_deviation#Corrected_sample_standard_d...]
But you probably searched for it and did not find it since it was abbreviated ...
indeed and we have a funky abbreviation. I started an interesting book on DSP for dummies (engineers like me) and I would like to see what we can do. www.dspguide.com. I like that he does not focus on math for their correctness. Stef

is stdev a typical name for standardDeviation?
Because I found it sad to have mean and stdev instead of mean and standardDeviation.
