EPPP TEST CONSTRUCTION UPDATED ACTUAL EXAM
QUESTIONS AND CORRECT ANSWERS
Question 1.
Classical Test Theory: Two methods of item analysis
ANSWER
1. Test difficulty
2. Item discrimination
Question 2.
Item difficulty is measured by calculating an item difficulty index, which is...
ANSWER
Total number of examinees passing the item /Total number of employees
Question 3.
Item discrimination
ANSWER
Refers to the extent to which a test item discriminates between examinees who obtain high
versus low scores on the entire test
Question 4.
Item discrimination index (D) is calculated by...
ANSWER
For each item, subtracting the percent of examinees in the lower-scoring group (L) from the
percent of examinees in the upper-scoring group (U) who answered the item correctly
Question 5.
Limitations of classical test theory
ANSWER
1. Item and test parameters are sample dependent
2. Difficult to equate scores obtained on different tests not developed on basis of classical test
theory
, Question 6.
Item Response Theory: Item characteristic curve
ANSWER
ICC is derived for each item by plotting the proportion of examinees in the tryout sample who
answered the item correctly against either the total test score, performance on an external
criterion, or mathematically derived estimate of a latent ability or trait
Question 7.
Item Characteristic Curve: Level of difficulty
ANSWER
Indicated by the ability level at which 50% of examinees in the tryout sample provided a
correct response
Question 8.
Item Characteristic Curve: Ability to discriminate
ANSWER
Indicated by the slope of the curve; the steeper the slope, the greater the discrimination
Question 9.
Item Characteristic Curve: Probability of guessing correctly
ANSWER
Indicated by the point at which the ICC intercepts the vertical axis
Question 10.
From the perspective of classical test theory, an examinee's obtained test score is composed of two
components, which are...
ANSWER
1. True score component
2. Error component
