QUESTION 1
The following type of test norms is an example of normalised standard scores.
A. Stanine scale
B. Percentiles
C. Z-scores
D. Mental age scales
Answer: C
normalised standard scores - A procedure in which each set of original scores is converted to
some standard scale under the assumption that the distribution of scores approximates that of a
normal.
a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. But
more technically it's a measure of how many standard deviations below or above the population mean
a raw score is.
QUESTION 2
Gradidge and De Jager 2011) evaluated the psychometric properties of the Wellness
Questionnaire for Higher Education. The Cronbach’s Alpha coefficients ranged between
0.80 and 0.96 for the seven subscales of the questionnaire and the test-retest coefficients
ranged between -0.04 and 0.71 for the seven subscales.
Internal consistency in this case refers to…
A. equivalence of two versions of the same test.
B. the degree of relatedness of items in a scale.
C. stability of the scores on the scales over time.
D. equivalence of two different tests.
Answer: B
Internal consistency reflects the extent to which items within an instrument measure various aspects of
the same characteristic or construct.
, QUESTION 3
There are advantages to test-retest reliability that do not apply to alternate-form reliability.
These include:
A. no transfer effects
B. less variation in the testing circumstances
C. lower costs
D. a small sample
Answer: C
The same test is administered twice to the same individuals over a period of time. (lower costs)
The correlation between the two tests of scores, T1 and T2, is known as the coefficient of stability.
