Criterion -related validity is a test’s correlation with the predicted outcome; do the scores on a scale correlate with external scores.

# data[].attributes.body
1. Face Validity: refers to the extent in which an assessment appears to measure what it is intended to. This results in a strong face validity.

2. Content Validity: evaluates whether a test covers all parts of a construct; test results will cover all parts of the construct that are relevant to what it is aiming to measure

3. Criterion Validity:

4. Predictive Criterion-Related Validity: A method of comparing a person’s scores on a test to their performance on activities that the test is designed to predict (criterion measure)  in which the test is administered first and then scores on the criterion measure are collected on the same group of people later on

Concurrent Criterion-Related Validity:The scores on the test and the criterion measure are collected at the same point in time

# data[].attributes.body
1. Face Validity – Determines whether the content of the assessment is consistent with the construct

2. Content Validity – widely used in educational testing and tests of aptitude/achievement; determines how well an individual has mastered a skill or content of course of study

3.Criterion –Related Validity – measures how well one measure predicts an outcome for another measure

4.    Predictive criterion-related validity – How well a measure predicts the occurrence of a concept

5.    Concurrent criterion-related validity – How well a new measure correlates with a previously validated measure of the same concept

# data[].attributes.body
Face Validity: extent to which it measures what it says it measures. The content of what a test looks like on the surface.
Content Validity:  When the test represents all aspects of the construct being measured.
Criterion Validity: Evaluates how closely the results of your test correspond to the results of a different test.
Predictive Criterion: A test that predicts scores on some measure eg. SAT
Concurrent Criterion: evidence that can gathered to defend the use of a test for predicting other outcomes.

# data[].attributes.body
1. Face Validity:

The transparency or relevance of a test as it appears to test participants.

2. Content Validity:

How well a test represents a construct.

3. Criterion –Related Validity

How a test relates to a concrete measurable outcome (to predict performance or behavior).

4. Predictive criterion-related validity

Measures future performance.

Concurrent criterion-related validity

The measurement of agreement between two different assessments.

# data[].attributes.body
1. Face validity: the actual answer given by participants and considered true by the adminstrators.
2. Content-related validity: used in education testing and is the measurement on how well an individual has mastered a scale.
3. Criterion-related validity: measures the scores compared to certain criteria/skills; i.e. GRE, SAT
4. Predictive criterion-related validity: a test is administered to collect criteria and then adminstered again at a later point in time to the same individuals.
5. Concurrent criterion-related validity: scores on criterion measure are collected at the same point in time

# data[].attributes.body
1. Face Validity
At a glance, the assessment appears to test what it means to test.
2. Content Validity
The content of the assessment relates to content that is being tested.
3. Criterion Validity
Test results relate to other tests looking at the same criteria.
4.Predictive Criterion Related Validity
Test results validate the results of a future test.
5. Concurrent Criterion Related Validity
Test results are compared at the same time to show validity.

1. Internal Consistency – estimates of reliability are based on average correlation among items within tests or scales

a) Split- half method - researcher divides questions into two halves (odd, even, or other strategy)

2. Test-retest reliability (temporal stability) – stability over time.  Same person consistently responds to same test, inventory or questionnaire administered on different occasions

3. Alternate-forms reliability (equivalent-forms reliability) –test administered to the same participants on two separate occasions

# data[].attributes.body
1.Internal consistency - measures the extent to which all parts of the test contributes equally.
2.The success of the split half method contributes or proves internal consistency.
3. Test-Retest-When the same test is given multiple times to the same group  to make sure the scores are consistent and valid.
Temporal Stability-Same test same group
4. Alternate forms- when different versions of the same test is given at different times.

# data[].attributes.body
1. Internal Consistency: the interrelationship of items on the same test.
a. Split-half method: measures internal consistency and the extent to which all parts of a test contribute equally.
2. Test-Retest Reliability: it measures the consistency by adminstering the same test multiple times.
3. Alternate Forms Reliability : individual is given alternate forms of the same test/assessment as a way to measure reliability.

# data[].attributes.body
1. Internal consistency: correlation among items within a test

2. Split-half method:  measures the range in which the different elements of the test contributes equally to what the test is trying to measure
test-retest reliability: how stable a person's scores are if they take the same assessment over multiple times. It estimates by the correlation between the scores of the same person taking the same test twice

3. alternate forms reliability: occurs when an individual participating in a research or testing scenario is given 2 different versions of the same test at different times.
criterion - related validity measures how well one measure predicts an outcome for another measure.  The extent to which people's scores correlate along to other variables.

# data[].attributes.body
1. Internal Consistency
- The general agreement between multiple items
- Ensures that all questions in a particular test relate/point to similar outcomes

1a. Split-half Method
- Assess the consistency of a particular test
- Compares results of one half a test to the results of another half of a test

2. Test-Retest Reliability (Temporal Stability)
- How close the results from a first test are to the results from a second test
- The conditions should be equal/similar to measure a test and retest
- Typically occurs when same person takes the same test multiple times

3. Alternate-Forms Reliability
- Two different versions of the same test

# data[].attributes.body
1.Internal Consistency
All of the items in a test correlate to each other.

a. Split-half method
If a test was split in half and given separately, the two halves would have the same result.

2.Test-retest Reliability (Temporal Stability)
Scores on a test are consistent when a person takes the test multiple times, over time.

3.Alternate –forms Reliability (Equivalent-forms Reliability)
Two equivalent versions of a test result in scores that correlate.

# data[].attributes.body
Internal Consistency: based on the average correlation among items within a test or scale
Split-half method: when one divides the questions into two halves and each half is a separate test- the total scores of these two half-tests for each participant are correlated together (can be split by odd or even numbered questions)
Test-retest reliability: the extent to which the same persons consistently respond to the same test given on different occasions
Alternate forms reliability: design two versions of the test that are similar in nature

VALIDITY:
Face validity: appearance of the measure itself and its test items
Content validity: how well a test measures particular characteristics or variables- can determine how well an individual has mastered a skill
Criterion-related validity- comparing scores on the test to scores on a selected criterion (academic achievement and achievement scores on tests)
Predictive criterion-related validity: test is administered first and then the scores on the criterion measure are collected on the sample at a later time
concurrent criterion-related validity: scores on the test and criterion measure are collected at the same time
