Validity Lecture 3

Question 1 of 17

1

What are constructs?

Select one of the following:

  • Unobservable, underlying already existing traits or characteristics that we can try and measure directly using tests

  • Observable, underlying hypothetical traits or characteristics that we can try and measure indirectly using tests

  • Observable, underlying already existing traits or characteristics that we can try and measure indirectly using tests

  • Unobservable, underlying hypothetical traits or characteristics that we can try and measure indirectly using tests

Explanation

Question 2 of 17

1

Statement 1: construct under-representation is the variation in an underlying construct that that is not captured by the measure
Statement 2: construct irrelevant variance is the variance that is not related to to the construct that is captured by the measure

Select one of the following:

  • Statement 1: false
    Statement 2: true

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Both are false

Explanation

Question 3 of 17

1

Statement 1: opinion-base validity measures include face and content validity
Statement 2: a measure with high validity has a small overlap between construct under-representation and construct irrelevant variance

Select one of the following:

  • Statement 1: false
    Statement 2: true

  • Both are true

  • Statement 1: true
    Statement 2: false

  • Both are false

Explanation

Question 4 of 17

1

Statement 1: tests may have good face validity without any actual validity
Statement 2: tests may have poor face validity while still having good actual validity

Select one of the following:

  • Statement 1: false
    Statement 2: true

  • Both are true

  • Both are false

  • Statement 1: true
    Statement 2: false

Explanation

Question 5 of 17

1

What type of validity is the following example demonstrating: a 3020 exam could have reasonable empirically-based validity without actually including any PSYC3020 content

Select one of the following:

  • Content validity

  • Face validity

  • Criterion validity

  • Convergent validity

Explanation

Question 6 of 17

1

How is content validity measured?

Select one of the following:

  • By getting novices and experts to both take the tests and comparing the differences

  • By getting the test-takers to rate how relevant the measure is to the construct

  • By getting experts to rate each question

  • By doing a factor analysis

Explanation

Question 7 of 17

1

Statement 1: measurements that are reliable are also valid
Statement 2: on the other hand, one can have a valid test if it is unreliable

Select one of the following:

  • Both are true

  • Statement 1: true
    Statement 2: false

  • Statement 1: false
    Statement 2: true

  • Both are false

Explanation

Question 8 of 17

1

What is the difference between non-random attrition and self-selection?

Select one of the following:

  • Non-random attrition: certain types of people dropping out of a longitudinal study
    Self-selection: only certain types of people are in your sample in the first place

  • Non-random attrition: different types of people dropping out of a longitudinal study
    Self-selection: random selection of people are in your sample

  • Non-random attrition: only certain types of people are in your sample in the first place
    Self-selection: certain types of people dropping out of a longitudinal study

  • Non-random attrition: random selection of people are in your sample
    Self-selection: certain types of people dropping out of a cross-sectional study

Explanation

Question 9 of 17

1

Statement 1: two factors that restrict the range of scores in a validity study is non-random attrition and self-selection
Statement 2: the validity coefficient always has to be above .70

Select one of the following:

  • Statement 1: false
    Statement 2: true

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Both are false

Explanation

Question 10 of 17

1

Statement 1: in criterion validity a method of contrasted groups is defined as test scores of groups of people varying as expected
Statement 2: criterion validity involves a 'criterion' that is a standard against which a test is evaluated

Select one of the following:

  • Statement 1: false
    Statement 2: true

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Both are false

Explanation

Question 11 of 17

1

What is criterion contamination?

Select one of the following:

  • The criterion that is being used to assess validity undermines the logic of criterion validity because the test scores of groups of people did not vary as expected

  • The criterion that is being used to assess validity undermines the logic of criterion validity because it failed to achieve high ratings from experts

  • The criterion that is being used to assess validity is determined after the test has been taken which undermines the logic of criterion validity

  • The criterion that is being used to assess validity is pre-determined by the test which undermines the logic of criterion validity

Explanation

Question 12 of 17

1

Statement 1: Concurrent validity is where a number of different predictors (tests) are used together
Statement 2: it is unimportant for both the test and its criterion to have decent reliability because the reliability is irrelevant to the size of the validity coefficient

Select one of the following:

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Statement 1: false
    Statement 2: true

  • Both are false

Explanation

Question 13 of 17

1

Statement 1: incremental validity is how much each individual predictor adds to predicting the criterion in addition to the effect of other predictors
Statement 2: predictive validity is a subset of criterion validity where the test is trying to predict what the criterion will be at some future time

Select one of the following:

  • Both are true

  • Both are false

  • Statement 1: true
    Statement 2: false

  • Statement 1: false
    Statement 2: true

Explanation

Question 14 of 17

1

Statement 1: There is no difference between discriminant and divergent validity
Statement 2: for incremental validity if two predictors are highly correlated then you should include both as each one is adding predictive power beyond the other

Select one of the following:

  • Both are true

  • Statement 1: true
    Statement 2: false

  • Statement 1: false
    Statement 2: true

  • Both are false

Explanation

Question 15 of 17

1

Statement 1: convergent validity is when test scores correlated with other measures of the same thing
Statement 2: discriminant/divergent validity is when tests scores do not correlate highly with measures that are not supposed to measure the same construct

Select one of the following:

  • Both are true

  • Statement 1: false
    Statement 2: true

  • Both are false

  • Statement 1: true
    Statement 2: false

Explanation

Question 16 of 17

1

What is the Wechsler Intelligence Scale for Children (WISC-IV)?

Select one of the following:

  • A test designed for children aged 10+ which contains 10 core subtests arranged into two groups (verbal comprehension, perceptual reasoning)

  • A test designed for children aged 10+ which contains 10 core subtests arranged into four groups (verbal comprehension, perceptual reasoning, long-term memory, processing speed)

  • A test designed for children aged 6-16 which contains 10 core subtests arranged into two groups (long-term memory, processing speed)

  • A test designed for children aged 6-16 which contains 10 core subtests arranged into four groups (verbal comprehension, perceptual reasoning, working memory, processing speed)

Explanation

Question 17 of 17

1

What is factor analysis?

Select one of the following:

  • Mathematical techniques are used to group items into clusters on the basis of how much they fail to correlate with each other

  • Mathematical techniques are used to group items into clusters on the basis of how much they correlate with each other referred to as internal structure

  • Mathematical techniques are used to group items into clusters on the basis of how much they correlate with each other and most of the time produce high correlations

  • Mathematical techniques are used to group items into clusters on the basis of how much they correlate with each other and most of the time produce low correlations
