Hello!
Suppose I have a column called 'Diff' in a dataset:
Diff
23.56
45.77
23.67
67.86
24.97
86.45
I want to calculate the standard deviation (a single value= 26.66928) of Diff (it's not a rolling standard deviation).
My variable for standard deviation is SD_A. What should be the code to get a single value of SD_A which I will need for further calculation?
Much thanks.
