Hi,
I am a beginner with ImageJ. I used it to calculate the mean and STDDEV value of a selected area in a picture of bacterial cell gotten from Nanosims. But I found the STDDEV is pretty big compare to the mean value. This will invalidate the mean value. So could you tell me the details of how this software calculate standard deviation?
Thanks very much
