Test (UT) deviation

Hi, Just would like to know how do you calculate UT thickness(spot) readings deviation for accuracy. Some people are telling me to take the (Max Reading - Min. Reading) / Average reading.
While some are practising the standard deviation formula in mathamatics.
Just would like to know the actual practice so that I can get an analysis of % deviation in thickness spot readings.

thanks guys
