,Q1. A university is implementing a new learning analytics dashboard to predict student at-risk status. The
system uses logistic regression on historical data including GPA, engagement metrics, and demographic
variables. After deployment, faculty notice that the model flags a disproportionate number of students from
underrepresented minority groups as at-risk, even when controlling for prior academic performance. Which
of the following best describes the primary ethical concern in this scenario?
A. Overfitting the model to training data
B. Algorithmic bias due to proxy discrimination
C. Low statistical power from small sample sizes
D. Violation of FERPA privacy regulations
Correct Answer: B. Algorithmic bias due to proxy discrimination
Rationale: Algorithmic bias occurs when a model systematically disadvantages certain groups. Even if race is not
a direct input, proxy variables (e.g., zip code, financial aid status) can correlate with race, leading to disparate
impact. Overfitting (A) is a technical issue but not the primary ethical concern here. Low power (C) may affect
reliability but not bias. Privacy (D) is important but the scenario focuses on fairness, not data exposure.
Why Wrong:
A - Overfitting would reduce generalizability but does not inherently produce group-based disparities.
C - Small sample sizes could increase variance but are not the direct cause of systematic bias against specific
groups.
D - FERPA violation would involve unauthorized disclosure of educational records, not predictive modeling
outcomes.

Analytics (pp. 61-75). Springer.
Q2. An assessment specialist is evaluating a 40-item multiple-choice test. The KR-20 reliability coefficient is
0.72. After removing five items with negative point-biserial correlations, the KR-20 increases to 0.85. Which
of the following best interprets this change?
A. The original test had high internal consistency but low content validity
B. The removed items were likely ambiguous or miskeyed, reducing reliability
C. The reliability increase is due to the test becoming shorter, which typically increases KR-20
D. The point-biserial correlations indicate the items were too easy for the sample
Correct Answer: B. The removed items were likely ambiguous or miskeyed, reducing reliability
Rationale: Negative point-biserial correlations indicate items that discriminate against high-performing students,
often due to flawed wording or incorrect answer keys. Removing such items improves internal consistency, raising
KR-20. KR-20 generally decreases with fewer items (not increases), so C is false. Content validity (A) is about
coverage, not reliability. Negative point-biserial does not directly indicate item difficulty (D).
Why Wrong:
A - Content validity is not assessed by reliability coefficients; the test could have high content validity despite
low reliability.
C - Reliability typically decreases when test length is reduced (Spearman-Brown prophecy), so a shorter test
would not raise KR-20 unless poor items are removed.
D - Point-biserial correlation measures discrimination, not difficulty; easy items can still have positive
discrimination.

Q3. A researcher applies item response theory (IRT) to calibrate a bank of mathematics items. For a given
item, the estimated discrimination parameter (a) is 0.4, and the difficulty parameter (b) is 1.5. Which of the
following is the most accurate interpretation?
A. The item is highly discriminating and moderately difficult
B. The item is poorly discriminating and very difficult
Page 3
, C. The item is highly discriminating and very easy
D. The item is poorly discriminating and very easy
Correct Answer: B. The item is poorly discriminating and very difficult
Rationale: In IRT, the discrimination parameter (a) typically ranges from 0 to 2+; values below 0.8 are considered low
discrimination. The difficulty parameter (b) is on a logit scale; 1.5 indicates a difficult item (higher b = harder). Thus a=0.4 is
poor discrimination, b=1.5 is high difficulty. Option B correctly identifies both.
Why Wrong:
A - A discrimination of 0.4 is low, not high; difficulty 1.5 is high, not moderate.
C - Discrimination is low, not high, and difficulty is high, not easy.
D - Difficulty is high, not easy.

Q4. A learning analytics team uses cluster analysis to group students based on their interaction patterns in an
online course. They identify three clusters: 'high engagers,' 'moderate engagers,' and 'low engagers.' The
team then examines final exam scores and finds that the mean scores differ significantly across clusters.
Which of the following additional analyses would best validate that the clusters represent meaningful
differences in learning rather than just activity levels?
A. Conduct a principal component analysis on the same interaction variables
B. Perform a discriminant function analysis to predict cluster membership from exam scores
C. Calculate the within-cluster sum of squares and compare with a null model
D. Examine the relationship between cluster membership and a separate outcome measure, such as a post-test
of conceptual understanding
Correct Answer: D. Examine the relationship between cluster membership and a separate outcome measure,
such as a post-test of conceptual understanding
Rationale: To validate that clusters represent learning differences, one should use an external criterion not used in
clustering. A separate outcome measure (e.g., conceptual post-test) provides convergent validity. PCA (A) is a
dimensionality reduction technique, not a validation. Discriminant analysis (B) would show predictability but not
independence from the clustering input. Within-cluster sum of squares (C) assesses internal cohesion, not external
meaning.
Why Wrong:
A - PCA would reduce variables but does not validate cluster meaning against an external outcome.
B - Discriminant analysis would be circular if based on the same variables used to form clusters.
C - Within-cluster sum of squares measures compactness, not whether clusters correspond to learning
differences.

Q5. In a competency-based assessment system, a student must demonstrate mastery of each learning
objective. The assessment uses a Bayesian knowledge tracing model to update the probability of mastery
after each practice opportunity. Initially, the prior probability of mastery for a skill is 0.2. The model
parameters are: guess = 0.1, slip = 0.1, and learning rate (transition from non-mastery to mastery) = 0.4.
After the student answers the first practice item correctly, what is the posterior probability of mastery?
A. 0.24
B. 0.32
C. 0.47
D. 0.56
Correct Answer: C. 0.47
Rationale: Using Bayes' theorem: P(mastery|correct) = [P(correct|mastery) * P(mastery)] /
[P(correct|mastery)*P(mastery) + P(correct|non-mastery)*P(non-mastery)]. P(correct|mastery) = 1 - slip = 0.9.
