How does the domain sampling model conceptualize reliability?
A)The absolute value of the difference between the standard error of measurement and the variance
B)The ratio of variance of the observed scores on the short version of a test and the variance of the long-run true scores
C)The sum of squares of the difference between the observed and true scores
D)The ratio of the number of sample items to the number of domain items, multiplied by the mean of the sample distribution

The domain sampling model conceptualizes reliability as the ratio of the variance of observed scores on a test to the variance of the true scores. This model suggests that observed scores are composed of true scores plus error, and reliability is a measure of how well the test scores reflect the true scores without the error.
