The function of the three reliabilities in learning and assessment are:
Test - retest reliability
Three types of Validity
Internal Consistency reliability
Three types of Reliability
Test -retest reliability is important for learning and assessment
Internal consistency reliability is important to learning and assessment
Reliability is the consistent results produced by measurement a devices.
Alternative reliability is important for learning and assessment
Construct validity is important to learning and assessment
Validity is the degree to which evidence support the accuracy of test -based inferences.
The meaning of content, criterion-related, and construct validity
Content validity is important for learning and assessments
The meaning of test-retest, alternative, and internal reliability
Reliability: Does it test yield consistent results.
Validity and reliability play a major role in learning and assessment. They provide the methods and tools necessary to conduct various forms of measurements. These methods and tools help guarantee that the tests are measuring what they are claiming to measure, and the measurements are consistent. Validity and reliability are refered to as the truthfulness of something.
Validity: Does it test measure what it claims to measure.
Criterion - related validity
Criterion - related validity is important to learning and assessment
The function of the three validities in learning and assessment are:
