If the mean value for a rating attribute was 3.2 for one sample, it might be 3.4 for a second sample of the same size. If we were to draw an infinite number ...

... From the definition of reliability given earlier (10), we note that the reliability of the combined measure is p2 / (p2 + 0.5*err2). However, from previous expressions we can see that either measure alone has a reliability of p2 / (p2 + err2). It is thus apparent that the combined measure is m ...
