1/5 · Identify the Research Questions
An analyst is cataloguing the research questions for a customer-churn initiative. One stakeholder asks, "What specific actions should we take next quarter to retain our highest-value at-risk customers?" Into which type of analytics question does this fall?
ADiagnostic — it asks why something happened.
BDescriptive — it asks what is happening based on historical data.
CPredictive — it asks what is likely to happen in the future.
DPrescriptive — it asks what action to take to achieve a desired outcome.
Show answer & explanation
D is correct. Research questions are commonly classified by the type of analytics they require: descriptive (what happened), diagnostic (why it happened), predictive (what is likely to happen), and prescriptive (what should be done). A question seeking recommended actions to optimize an outcome is prescriptive. Recognizing the question type guides the analyst toward the appropriate analytical approach.

An airline wants to study on-time performance and frames the question: "What factors most influence delays?" During refinement, the analyst realizes the team is split: some assume each row of data should represent an individual flight, others a route, and others an entire travel day at an airport. Resolving this disagreement primarily clarifies which aspect of the research question?
AThe unit of analysis — the entity each observation represents — which determines how data is aggregated and how findings are interpreted.
BWhich predictive algorithm will best handle delay data.
CWhether the data should be stored in a relational or columnar database.
DThe sample size needed to reach statistical significance for the chosen test.
Show answer & explanation
A is correct. A well-framed research question specifies the unit of analysis — the entity (flight, route, customer, transaction, day) that each data observation represents. Ambiguity here leads to incompatible data preparation and misinterpreted results. Settling whether the team studies flights, routes, or airport-days defines the unit of analysis before sourcing and structuring data.

A retail chain's executive sponsor states the business problem as: 'Our customer loyalty program is underperforming.' Before any data is sourced, the analytics team needs to convert this into something a data analysis effort can act on. Which of the following best represents the team's most appropriate immediate next step?
AImmediately query the loyalty database and build a dashboard so the sponsor can explore the data interactively
BSelect a predictive modeling algorithm appropriate for churn so results are ready when questions arise
CDocument the data quality issues in the loyalty database so they can be remediated
DDecompose the vague problem statement into specific, answerable research questions that target measurable aspects of loyalty program performance
Show answer & explanation
D is correct. The core purpose of identifying research questions is to convert a broad, often vague business problem into specific and answerable questions. Only once those questions exist can the team determine what data is needed, which techniques apply, and how results will be reported. Jumping to data, tools, or quality work first is a common failure mode.

4/5 · Identify the Research Questions
A research question requires linking individual web-session behavior to in-store purchases, but the company has no way to connect anonymous web visitors to identified store transactions. Within the activity of identifying research questions, what is the appropriate response to this finding?
AKeep the question unchanged and let the visualization stage resolve the gap
BProceed with the analysis and assume the missing linkage by randomly matching records
CReport that the business problem cannot be analyzed at all and close the initiative
DReassess the question for feasibility and either narrow it to what available data can support or seek a means to obtain the linking data

5/5 · Identify the Research Questions
An operations team frames: "Did the new dispatch algorithm improve delivery times?" A senior analyst replies, "Improve compared to what?" and insists this be resolved before the question is accepted. What is the senior analyst requiring the question to specify?
AThe statistical significance threshold the result must clear
BThe privacy controls needed before delivery data can be used
CA baseline or benchmark—the reference point (e.g., pre-change performance or an industry standard) against which 'improvement' will be measured
DThe unit of analysis for the delivery records
Show answer & explanation
C is correct. Any research question that asserts change—improve, increase, reduce—needs an explicit baseline or benchmark. Without a defined reference point (prior period, control group, or external standard), 'improvement' cannot be measured and the question is not yet answerable.
