Validity
refers to the degree to which a test measures what it is supposed to measure.
When a test is actually measuring what it is supposed to measure it is said that the test has?
If the test does indeed measure this, then it is said to have
content validity —
it measures what it is supposed to measure. also called predictive validity, measures the degree to which the test scores measuring one test criterion is consistent with other criterion being measured.
When a test measures what it is intended to measure it is said to be from book?
3.
Validity
: For a test to be usable, it should also be valid. It refers to the extent to which the test measures what it intends to measure.
When a psychological test measures what it was designed to measure we can say that the test has?
One of the greatest concerns when creating a psychological test is whether or not it actually measures what we think it is measuring.
Validity
is the extent to which a test measures what it claims to measure. It is vital for a test to be valid in order for the results to be accurately applied and interpreted.
When an instrument really measures what it is supposed to measure it is said to have ?
Validity
refers to the accuracy of a measurement instrument (if it indeed measures what it says it does).
What are the 3 types of reliability?
Reliability refers to the consistency of a measure. Psychologists consider three types of consistency:
over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater reliability)
.
Which of the following is a reliable measure?
Answer is “
Temperature
“
How do you determine the validity of a questionnaire?
- Establish face validity.
- Conduct a pilot test.
- Enter the pilot test in a spreadsheet.
- Use principal component analysis (PCA)
- Check the internal consistency of questions loading onto the same factors.
- Revise the questionnaire based on information from your PCA and CA.
Is reliable test always valid?
How do they relate?
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.
What is reliability of test?
The reliability of test scores is
the extent to which they are consistent across different occasions of testing
, different editions of the test, or different raters scoring the test taker’s responses.
What are the factors that influence validity?
- Population characteristics (subjects)
- Interaction of subject selection and research.
- Descriptive explicitness of the independent variable.
- The effect of the research environment.
- Researcher or experimenter effects.
- Data collection methodology.
- The effect of time.
What’s an example of validity?
The concept of validity was formulated by Kelly (1927, p. 14) who stated that a
test is valid if it measures what it claims to measure
. For example a test of intelligence should measure intelligence and not something else (such as memory).
What is an example of validity?
Validity refers to
how well a test measures what it is purported to measure
. … For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs.
When a scale measures what it is supposed to measure it is said to have quizlet?
The extent to which a test measures what it is supposed to measure. You just studied 21 terms!
How will you determine the reliability of your instrument?
Reliability can be assessed with
the test-retest method, alternative form method, internal consistency method, the split-halves method, and inter-rater reliability
. Test-retest is a method that administers the same instrument to the same sample at two different points in time, perhaps one year intervals.
What is an example of construct validity?
Construct validity refers to whether a scale or test measures the construct adequately. An example is a
measurement of the human brain
, such as intelligence, level of emotion, proficiency or ability. … Construct validity is valuable in social sciences, where there is a lot of subjectivity to concepts.
