NCE NCE Appraisal and Testing 2 — Questions and Answers
Question 1: A correlation coefficient of -0.80 indicates:
- A weak positive relationship
- A strong positive relationship
- A strong negative relationship (Correct answer)
- No meaningful relationship
Correct answer: A strong negative relationship
A correlation of -0.80 indicates a strong inverse relationship in which one variable increases as the other decreases.
Question 2: The test-retest reliability method is used to assess:
- Internal consistency of items
- Stability of scores over time (Correct answer)
- Agreement between two raters
- Breadth of content coverage
Correct answer: Stability of scores over time
Test-retest reliability measures whether a test produces stable scores when given to the same group at two different time points.
Question 3: A percentile rank of 75 indicates that the examinee scored:
- Correctly on 75% of questions
- At or above 75% of the normative group (Correct answer)
- Below 75% of the normative group
- At exactly the 75th item
Correct answer: At or above 75% of the normative group
A percentile rank of 75 means the examinee scored at or above 75% of individuals in the normative sample.
Question 4: Which test is most widely used to assess cognitive ability in adults?
- Stanford-Binet Intelligence Scale
- Wechsler Adult Intelligence Scale (WAIS) (Correct answer)
- Kaufman Assessment Battery for Children
- Raven's Progressive Matrices
Correct answer: Wechsler Adult Intelligence Scale (WAIS)
The WAIS is the most widely used standardized instrument for assessing intellectual functioning in adults.
Question 5: Which statistic represents the middle value in a ranked distribution of scores?
- Mean
- Mode
- Median (Correct answer)
- Range
Correct answer: Median
The median is the middle score when all values are arranged in ascending or descending order, dividing the distribution in half.
Question 6: Split-half reliability is used to estimate:
- Stability of scores over time
- Agreement between raters
- Internal consistency from a single administration (Correct answer)
- Predictive validity
Correct answer: Internal consistency from a single administration
Split-half reliability divides a single test into two halves and correlates the scores to estimate internal consistency without requiring two test sessions.
