Detailed Answer in Step-by-Step Solution:
Objective: Identify the initial data science step.
Define Process: Starts with problem definition, then data and modeling. Evaluate Options:
A: Data collection—Second step after problem definition. B: Modeling—Later stage.
C: Hypothesis—Sets the goal, first step—correct. D: Data owners—Collaboration, not the start.
Reasoning: Hypothesis drives the process (e.g., “Can we predict churn?”). Conclusion: C is correct.
OCI documentation states: “The data science process begins with defining an analytical hypothesis to
address a business problem, followed by data collection and analysis.” C precedes A, B, and D— aligning
with OCI’s structured approach.
