Dr.Smith is trying to determine the reliability of a new personality test.Two randomly parallel tests,A and B,have a correlation of .81.What is the estimated reliability of the new personality test?
Professor Pine constructed five different short history tests by randomly drawing questions from the huge pool of all possible questions about the current material.He has created
A) randomly parallel tests.
B) a large sample size.
C) systematic errors.
D) attenuation effects.
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
Why might different random samples of domain items yield different estimates of the true score?
A) sampling error
B) poor reliability
C) respondent error
D) item bias
