EDF 4430 Chapter 3 Reliability Exam
Questions With Correct Answers
Define Reliability in terms of tests - CORRECT ANSWER✔✔-Consistency of the test
| | | | | | | | | | |
in measuring that it's measuring
| | | | |
Extent to which scores are free from random measurement error
| | | | | | | | |
Inconsistent test scores often yield ________ - CORRECT ANSWER✔✔-Inaccurate
| | | | | | | | |
inferences
Explain how reliability is measured - CORRECT ANSWER✔✔-Measured using
| | | | | | | | |
some statistical index
| | |
often a correlation coefficient
| | | |
Reliability ranges between 0 and 1 | | | | |
| 0 means no consistency between scores
| | | | |
| 1 means perfect agreement between scores
| | | | |
Correlation Coefficient - CORRECT ANSWER✔✔-Correlation coefficients are used
| | | | | | | |
to indicate strength of a linear relationship
| | | | | |
For reliability, indicates degree of consistency between two tests
| | | | | | | |
3 Types of Reliability - CORRECT ANSWER✔✔-Test-retest - Stability over time
| | | | | | | | | |
Alternate-forms - Equivalency of two forms of an assessment | | | | | | | |
, Internal consistency - Degree of homogeneity in assessment items
| | | | | | | |
Discuss test re-test reliability - CORRECT ANSWER✔✔-Measures stability of test
| | | | | | | | | |
scores over time| |
Test is administer twice
| | |
Example: Pretest-posttest
| |
Calculate the correlation coefficient between the two sets of responses
| | | | | | | | |
Alternative-Forms Reliability - CORRECT ANSWER✔✔-Measures equivalence of
| | | | | | |
the two forms
| |
Two forms of an assessment are designed to measure same concept
| | | | | | | | | |
Administer two forms of the assessment to the same group
| | | | | | | | |
Calculate the correlation coefficient between the two sets of responses
| | | | | | | | |
Internal-Consistency Reliability - CORRECT ANSWER✔✔-Measures consistency | | | | | |
between the items of the assessment
| | | | |
Situation: Construct one form of an assessment
| | | | | |
Administer the assessment | |
Calculate Kuder-Richardson 20 or Cronbach's coefficient alpha
| | | | | |
Classification-Consistency Reliability - CORRECT ANSWER✔✔-Used with two | | | | | | |
administrations of a test (test-retest) or two forms of a test (alternative-forms)
| | | | | | | | | | |
|Test results are used to classify test-takers into one of two categories (Example:
| | | | | | | | | | | | |
Pass-fail)
