• Types of tests
• Applications of tests

The course includes applying knowledge in assignments.

Question 2

Name the types of testing illustrated in the course.

Answer 2

• Intelligence testing
• Personality testing
• Diagnostic testing
• Educational testing

These types are essential for understanding psychological assessments.

Question 3

What is the title of the book used in the course?

Answer 3

Psychological Testing, a Practical Introduction

By Thomas P. Hogan, editions 3rd and 4th.

Question 4

What are the three assignments in the course?

Answer 4

• Reliability analysis
• Structure of a test
• Predictive validity

Assignments must be submitted individually via Brightspace.

Question 5

True or false: Assignments in Test theory (PSBE2-06) are graded as ‘pass’ or ‘fail’.

Answer 5

TRUE

Passing is required for participation in the exam.

Question 6

What is the definition of a test in psychological testing?

Answer 6

A standardized process or device that yields information about a sample of behavior or cognitive processes in a quantified manner

This definition emphasizes the importance of standardization.

Question 7

What are the basic assumptions of psychological testing?

Answer 7

• Humans have traits or characteristics
• Differences in traits are important
• Traits can be quantified
• Traits are reasonably stable
• Measures relate to actual behavior

These assumptions underpin the validity of psychological assessments.

Question 8

What is norm-referenced testing?

Answer 8

Comparing an individual test score with test scores in a population

This helps interpret the score in relation to others.

Question 9

What are the major types of norms in psychological testing?

Answer 9

• Percentile ranks
• Standard scores
• Developmental norms

These norms help in interpreting raw scores meaningfully.

Question 10

What does a z-score represent?

Answer 10

Z scores = (X - M) / SD

Z scores have a mean of 0 and SD of 1.

Question 11

What is the formula for calculating percentile ranks?

Answer 11

Pr = (B / N) * 100

Where B is the number of scores smaller than X and N is the total number of scores.

Question 12

What are standard scores used for?

Answer 12

Transformation from raw score to a convenient mean and standard deviation

Common types include T-scores, SATs, and Deviation IQ.

Question 13

What are developmental norms used for?

Answer 13

• Mental Age
• Grade equivalents

These norms help assess whether development is proceeding normally.

Question 14

What is the basic idea of criterion-referenced interpretation?

Answer 14

Interpret a test score without reference to any norm group

For example, setting a passing score of 55%.

Question 15

A child with a score of 42 has a mental age of __________.

Answer 15

7 years and 4 months

This score indicates the developmental level of the child compared to age norms.

Question 16

What are developmental norms used for?

Answer 16

Relating median performance in each grade instead of ages

This allows for obtaining grade equivalent norms.

Question 17

Define criterion-referenced interpretation.

Answer 17

Interpreting a test score without reference to any norm group

For example, a student needs a 55% correct score to pass an exam.

Question 18

True or false: Criterion-referenced interpretation is useful when you have a well-defined body of content.

Answer 18

TRUE

It is widely used for setting proficiency levels in educational testing.

Question 19

For the last year test theory exam, at least a score of X = __________ is needed to pass.

Answer 19

43

This is based on a test consisting of 60 items.

Question 20

Summarizing the lecture, we talked about: What is a test? Why are we using tests? What are norms?

Answer 20

Different norms and how to calculate different norms

These are key concepts discussed in the lecture.

Question 21

Next week, we will cover item analysis, which includes __________.

Answer 21

• Item popularity
• Item discrimination (p-value, item-test correlations)
• Reliability

These topics are essential for understanding test quality.
