How is content validity measured?

Selecciona una de las siguientes respuestas posibles:

  • 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

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

Selecciona una de las siguientes respuestas posibles:

  • 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

Pregunta 10 de 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

Selecciona una de las siguientes respuestas posibles:

  • Statement 1: false
    Statement 2: true

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Both are false

Explicación

Pregunta 11 de 17

1

What is criterion contamination?

Selecciona una de las siguientes respuestas posibles:

  • 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

Explicación

Pregunta 12 de 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

Selecciona una de las siguientes respuestas posibles:

  • Statement 1: true
    Statement 2: false

  • Both are true

  • Statement 1: false
    Statement 2: true

  • Both are false

Explicación

Pregunta 13 de 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

Selecciona una de las siguientes respuestas posibles:

  • Both are true

  • Both are false

  • Statement 1: true
    Statement 2: false

  • Statement 1: false
    Statement 2: true

Explicación

Pregunta 14 de 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

  • Both are true

  • Statement 1: true
    Statement 2: false

  • Statement 1: false
    Statement 2: true

  • Both are false

Explicación

Pregunta 15 de 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

  • Statement 1: false
    Statement 2: true

  • Both are false

  • Statement 1: true

What is factor analysis?

Selecciona una de las siguientes respuestas posibles:

  • 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
