Question 7

Classical Test theory assumes that the true score for an individual will not change with related applications for the same test (hence ________)

Answer 7

reliability

Question 8

The S_______ D________ of the distribution of errors for each person tells us about the magnitude of measurement error

Answer 8

Standard Deviation
