Which of the following statements best describes construct validity? It refers to the adequacy of the operational definition of variables. Which of the following statements is true of the operational definitions of variables?
Detailed Solution. The correct answer is "A valid test is always reliable".
Correct answer is: A valid test must be reliable. A valid test must be reliable.
What is construct validity? Construct validity concerns the extent to which your test or measure accurately assesses what it's supposed to. In research, it's important to operationalize constructs into concrete and measurable characteristics based on your idea of the construct and its dimensions.
Validity can be defined as the agreement between a test score or measure and the quality it is believed to measure.
Which of the following is the best statement regarding the relationship between different forms of validity in psychology research? It is difficult to achieve high levels of both internal and external validity in the same research study.
Terms in this set (10) Which of the following is true of the relationship between reliability and validity? It is possible to create a highly reliable test that lacks validity.
There are four main types of validity: Construct validity: Does the test measure the concept that it's intended to measure? Content validity: Is the test fully representative of what it aims to measure? Face validity: Does the content of the test appear to be suitable to its aims?
The two measures may be for the same construct, but more often used for different, but presumably related, constructs. The two measures in the study are taken at the same time. This is in contrast to predictive validity, where one measure occurs earlier and is meant to predict some later measure.
Construct validity is a device used almost exclusively in social sciences, psychology and education. For example, you might design whether an educational program increases artistic ability amongst pre-school children.
Construct validity is an assessment of how well you translated your ideas or theories into actual programs or measures.
Combining convergent and discriminant validity To combine the two and quantify overall construct validity, subtract the discriminant coefficient from the convergent coefficient.
A reliable measurement is not always valid: the results might be reproducible, but they're not necessarily correct. A valid measurement is generally reliable: if a test produces accurate results, they should be reproducible.
Terms in this set (10) Which of the following is true of the relationship between reliability and validity? It is possible to create a highly reliable test that lacks validity.
Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
When discussing the relationship between reliability and validity, which of the following is true? Low reliability always indicates low degree of validity.
Differentiate between content and construct validity: Construct refers to a theoretical concept (construct), while content refers to an established ability (i.e addition, multiplication, driving)
Criterion Validity: The degree to which the instrument correlates with one or more outcome criteria.
If CVR is negative, less than half the raters agree that it is. If CVR is zero, exactly half the raters agree that it is; and if CVR is positive, over half the raters agree that it is. More simple method: Just have raters identify whether the item should belong on the test and calculate inter-rater reliability.
Incremental Validity - The degree to which additional predictors explain something about the outcome that are not already explained by the predictors already in use.
Tap card to see definition 👆. Validity refers to the degree of which a test measure what it is intended to measure within a given context. No such thing as a test having "universal validity" - rather, a test can be proven valid for a particular use with a particular population.
Construct - Unobservable, but scientifically sound concepts constructed to describe or explain behavior
Face Validity: The extent to which a measure appears (superficially) to assess construct of interest - not a formal validation procedure. Does not depend on established theories for support
