What does reliability refer to in assessments?
Fairness of test content to all demographic groups
Degree to which a test measures the intended construct
Consistency of scores across repeated administrations
Accuracy of score interpretation
Reliability refers to the consistency or stability of test scores across repeated administrations. Validity, by contrast, refers to the extent a test measures what it purports to measure.
Which type of validity assesses whether test content covers the intended domain?
Criterion validity
Construct validity
Face validity
Content validity
Content validity examines how well test items represent the full range of the construct domain. It ensures that the content matches the intended subject matter.
Which reliability type examines the consistency of scores over repeated administrations?
Test-retest reliability
Split-half reliability
Alternate-forms reliability
Inter-rater reliability
Test-retest reliability measures the stability of scores over time by administering the same test twice. High correlation between administrations indicates strong reliability.
Inter-rater reliability evaluates:
Coverage of content domain
Consistency of scores over time
Agreement between different scorers
Precision of item wording
Inter-rater reliability assesses the degree to which different raters give consistent scores to the same responses. It helps identify scoring biases between evaluators.
What is a common source of measurement error that threatens reliability?
Outdated scoring rubric
Bias in item content
Random fluctuations in test-taker performance
Insufficient content coverage
Random fluctuations, such as variations in attention or fatigue, introduce unsystematic error that reduces reliability. Systematic errors like bias are different threats.
A Cronbach's alpha of 0.85 indicates:
High internal consistency of items
Low difficulty of test items
High face validity of the test
Strong predictive validity
Cronbach's alpha measures internal consistency reliability, with values closer to 1 indicating that items are highly interrelated. A value of 0.85 is considered strong.
Which practice would most likely improve a test's reliability?
Using more subjective scoring methods
Increasing item difficulty uniformly
Increasing the number of test items
Shortening the testing time significantly
Adding more items typically increases reliability by reducing the impact of random error. Subjective scoring or shortening the test can introduce more variability.
Criterion validity is concerned with:
Degree to which test content covers a domain
Appearance of appropriateness to takers
Correlation between test scores and an external outcome
Internal consistency of test items
Criterion validity evaluates how well test scores relate to an external measure (the criterion), such as job performance or academic success. It includes concurrent and predictive validity.
A test that correlates highly with another established measure administered at the same time demonstrates:
Predictive validity
Content validity
Construct validity
Concurrent validity
Concurrent validity is shown when scores on a new test align closely with scores from an established test measured at the same time. Predictive validity involves future outcomes.
Which validity type refers to the surface appearance of test appropriateness?
Face validity
Construct validity
Content validity
Criterion validity
Face validity addresses whether a test appears suitable to test-takers or stakeholders. It does not guarantee actual measurement accuracy but affects acceptance.
Which threat to measurement accuracy is systematic rather than random?
Test bias against a subgroup
Random environmental noise
Temporary fluctuations in attention
Accidental scoring errors
Systematic errors, such as bias against certain groups, consistently skew scores in one direction. Random errors like noise vary unpredictably.
The Kuder-Richardson Formula 20 (KR-20) is used to assess:
Content validity
Inter-rater reliability
Test-retest reliability
Internal consistency of dichotomous items
KR-20 calculates internal consistency for tests with right/wrong scoring. It estimates how consistently items measure a single construct.
Split-half reliability involves:
Comparing different raters' scores
Measuring stability over time
Correlating scores from two halves of the same test
Comparing two alternate forms
Split-half reliability divides a test into two parts and examines the correlation between them. A higher correlation indicates greater internal consistency.
Discriminant validity ensures that a test:
Predicts future performance
Does not correlate strongly with unrelated constructs
Has high internal consistency
Covers all topics of the domain
Discriminant validity demonstrates that a measure is distinct from other constructs it should not be related to. It helps confirm the uniqueness of the target construct.
Which strategy enhances test fairness?
Using culturally biased language
Increasing item difficulty for all groups
Providing appropriate accommodations
Ignoring demographic differences
Providing accommodations such as extra time or alternative formats helps ensure that valid scores reflect ability rather than barriers. Ignoring group differences undermines fairness.
In generalizability theory, the generalizability coefficient represents:
Proportion of total variance attributable to true score variance
Correlation between two alternate test forms
Amount of random error variance
Degree of content representativeness
The generalizability coefficient in G-theory quantifies the ratio of true score variance to total variance, including error sources. It extends classical reliability by modeling multiple error facets.
The multitrait-multimethod matrix is used to evaluate:
Internal consistency of scales
Convergent and discriminant validity across traits and methods
Predictive validity for future outcomes
Test-retest reliability across forms
The multitrait-multimethod matrix assesses both convergent validity (traits measured by different methods correlate) and discriminant validity (different traits do not correlate).
A low standard error of measurement (SEM) indicates:
Low reliability of the test
Poor content coverage
High systematic bias
High precision of individual scores
SEM reflects the expected spread of observed scores around a true score. A low SEM means observed scores are tightly clustered, indicating precise measurement.
In item response theory, the difficulty parameter indicates:
The overall length of the test
The guessing probability on a multiple-choice item
The discrimination power of an item
The trait level needed for a 50% chance of a correct response
In IRT, the difficulty parameter (often called b) locates the point on the latent trait scale where a test-taker has a 50% chance of answering correctly. It differs from discrimination and guessing parameters.
Predictive validity is best demonstrated when test scores:
Accurately forecast future performance outcomes
Match the content outline of the test
Have high internal consistency reliability
Are consistent over repeated administrations
Predictive validity shows how well test scores predict future behavior or performance. A strong correlation between test results and later outcomes indicates good predictive validity.

Cheat Sheet

  1. Understanding Reliability - Reliability is all about consistency: imagine hitting the bullseye every single time under the same conditions. If you retake a vocabulary quiz and the scores line up, your assessment tool is reliable. Dive deeper into reliability
    2. chfasoa.uni.edu
  2. Types of Reliability - There are nifty flavors of reliability like test-retest, parallel forms, and internal consistency, each checking consistency in different ways. Test-retest checks stability over time, parallel forms compare two equivalent versions, and internal consistency sees how well your questions hang together. Explore reliability types
    3. chfasoa.uni.edu
  3. Understanding Validity - Validity is the "truth-teller" of your test; it shows that your assessment measures exactly what you want it to. A valid math test actually assesses math skills, not just reading comprehension or test-taking tricks. Learn what makes a test valid
    4. chfasoa.uni.edu
  4. Types of Validity - Validity comes in flavors too: content, criterion-related, and construct validity make sure you cover the right topics, predict outcomes accurately, and measure the theoretical ideas you intend. Content validity checks coverage, criterion-related links scores to real-world results, and construct validity confirms you're truly measuring the target concept. Dig into validity types
    5. chfasoa.uni.edu
  5. Reliability vs. Validity - Think of reliability as repeatability and validity as accuracy: your quiz can be consistent but still miss the mark (like a clock that's always five minutes slow). To truly rock your assessments, you need both stars aligned! See the relationship
    6. chfasoa.uni.edu
  6. Factors Affecting Reliability - Elements like test length, environment, instructions, and student mood can shake up your reliability score. Short quizzes might feel wobbly, noisy rooms distract brains, and fuzzy instructions leave students guessing. Check out reliability factors
    7. vaia.com
  7. Boosting Reliability - Standardize test conditions, craft crystal-clear questions, and train your raters well to keep those scores steady. Consistency is king - uniform setups lead to trustable results. Get improvement tips
    8. chfasoa.uni.edu
  8. Reading Reliability Coefficients - Reliability coefficients range from 0 (uh-oh) to 1.0 (perfect): above .9 is top-tier, .8 - .89 is solid, .7 - .79 is acceptable, and below .7 might need a reliability tune-up. Knowing these thresholds helps you judge if your test's consistency is up to snuff. Interpret coefficients
    9. hr-guide.com
  9. Reading Validity Coefficients - Validity coefficients also go from 0 to 1, but most sit below .4 since predicting real-world outcomes is trickier than pure consistency. A higher coefficient still signals a strong link between your test and the criteria you care about. Understand validity stats
    10. hr-guide.com
  10. Ensuring Fairness - Fairness means bias reviews, mixed question styles, and accommodations for all learners - think universal design! By checking items for cultural slants, varying formats, and supporting diverse needs, your test welcomes every student. Fairness strategies
