B) lower than the validity coefficients found in the original validation study
C) higher than the validity coefficients found in the original validation study
D) unrelated to the validity coefficients found in the original validation study

Quizplus · Accepted Answer

The validity coefficients that result when a test is cross-validated are usually expected to be lower than the validity coefficients found in the original validation study. This is because cross-validation assesses the predictive ability of the test on a new sample, which may differ from the original validation sample in terms of characteristics such as age, gender, or cultural background. Therefore, the lower validity coefficients may reflect the test's inability to generalize to new samples or populations.
