Dear all,
standard error of measurement is used to test the reliability of a measuring
device, and is calculated by the following equation:
SEM = s(1.00 - r)^0.5
I need some advice on the meaning of the variables "s" and "r". "r"
obviously stands for a correlation value between two sets of data (or two
tests), and "s" stands for the the standard deviation of one set of data or
the combined set of data (two tests).
An example would be wonderful!
Cheers,
Noel
