  3. Normality
  4. Skewness
Question 3 Multiple Choice (Single Answer)

What is the difference between internal consistency and inter-rater reliability?

  1. Internal consistency refers to the agreement among different items within a test, while inter-rater reliability refers to the agreement among different raters assessing the same individual.
  2. Internal consistency refers to the agreement among different raters assessing the same individual, while inter-rater reliability refers to the agreement among different items within a test.
  3. Both internal consistency and inter-rater reliability refer to the agreement among different raters assessing the same individual.
  4. Both internal consistency and inter-rater reliability refer to the agreement among different items within a test.
Question 4 Multiple Choice (Single Answer)

Question 6 Multiple Choice (Single Answer)

What is the difference between a norm-referenced test and a criterion-referenced test?

  1. A norm-referenced test compares an individual's performance to the performance of a normative group, while a criterion-referenced test compares an individual's performance to a predetermined standard.
  2. A norm-referenced test compares an individual's performance to a predetermined standard, while a criterion-referenced test compares an individual's performance to the performance of a normative group.
  3. Both norm-referenced and criterion-referenced tests compare an individual's performance to a predetermined standard.
  4. Both norm-referenced and criterion-referenced tests compare an individual's performance to the performance of a normative group.
