Standard deviation of data after data treatment

[Baho Ilok]

I was given the averages (AVG) and the corresponding standard deviation (SD) of sets of data. I have no copy of the raw data for each data point that were used to calculate the AVG and SD.

I performed further data treatment on the data. I want to ask what is the relationship between the original SDs and the SDs of my treated data.

Thank you!

That depends on the treatment you did.
Error propagation will tell you what to do.
