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!
