Section A: Epistemology & Knowledge Formation — How We Know
What We Know (8 Questions)
Q1: A data science student argues that knowledge about customer purchasing patterns
can only be considered valid if it is derived from observable, measurable transactions
recorded in a database. Which epistemological tradition best reflects this student's
position?
A. Rationalism
B. Interpretivism
C. Positivism [CORRECT]
D. Constructivism
Correct Answer: C
Rationale: Positivism holds that valid knowledge comes from observable, measurable
phenomena and objective reality; rationalism emphasizes reason over observation,
interpretivism values subjective meaning, and constructivism views knowledge as
socially constructed rather than objectively discovered.
Q2: A researcher develops a theoretical model predicting that increased social media
usage causes decreased attention span, then designs an experiment to test whether
observed data align with this theoretical prediction. Which reasoning process is
primarily being employed?
A. Inductive reasoning
B. Deductive reasoning [CORRECT]
C. Abductive reasoning
D. Analogical reasoning
Correct Answer: B
,Rationale: Deductive reasoning moves from general theory to specific testable
hypotheses; the researcher starts with a general prediction and tests it against specific
observations, whereas inductive reasoning would derive general patterns from specific
observations.
Q3: A team of data scientists notices that users who engage with recommendation
feature X also have higher retention rates, leading them to propose the general rule that
"feature X drives retention." Which reasoning process does this represent?
A. Deductive reasoning
B. Inductive reasoning [CORRECT]
C. Abductive reasoning
D. Circular reasoning
Correct Answer: B
Rationale: Inductive reasoning derives broad generalizations from specific observations;
the team moves from specific user behavior patterns to a general claim about
causation, which is characteristic of inductive inference rather than theory-driven
deduction.
Q4: A hospital administrator notices a sudden spike in patient readmissions and infers
that a recent change in discharge protocols is the most likely explanation, despite
incomplete information. Which reasoning mode best describes this inference?
A. Deductive reasoning
B. Inductive reasoning
C. Abductive reasoning [CORRECT]
D. Reductive reasoning
Correct Answer: C
Rationale: Abductive reasoning involves inferring the most plausible explanation from
incomplete information; the administrator selects the best available hypothesis
(discharge protocol change) to explain an observed phenomenon without definitive
proof.
Q5: A data scientist consistently interprets ambiguous model results as confirming her
initial hypothesis that a new algorithm outperforms the legacy system, while dismissing
contradictory evidence as "noise." Which cognitive bias is most clearly operating?
A. Anchoring bias
, B. Confirmation bias [CORRECT]
C. Availability heuristic
D. Base rate neglect
Correct Answer: B
Rationale: Confirmation bias is the tendency to seek, interpret, and remember
information in ways that confirm preexisting beliefs while discounting disconfirming
evidence; anchoring involves over-relying on first information, and availability involves
judging probability by ease of recall.
Q6: A qualitative researcher studying user experience insists that the "truth" of whether
a software interface is intuitive depends entirely on the subjective meanings users
assign to their interactions, not on objective task-completion metrics. Which
epistemological stance does this reflect?
A. Positivism
B. Empiricism
C. Interpretivism [CORRECT]
D. Logical positivism
Correct Answer: C
Rationale: Interpretivism emphasizes that knowledge and truth are constructed through
subjective meaning and contextual understanding; it rejects the notion of a single
objective reality in favor of multiple constructed realities, contrasting with positivism
and empiricism.
Q7: A capstone student recognizes that his own cultural background influences which
variables he selects as important in a predictive model, and he actively documents
these assumptions to make his reasoning transparent. Which epistemological principle
is he practicing?
A. Pure objectivity
B. Epistemological pluralism and reflexivity [CORRECT]
C. Radical relativism
D. Foundationalism
Correct Answer: B
Rationale: Acknowledging and documenting the influence of perspective on knowledge
creation reflects epistemological pluralism and reflexivity, which values transparency
about subjectivity rather than claiming pure objectivity or embracing radical relativism.
