Ciara is going to college to become a data scientist for an insurer. Which of Ciara's skills will require her to understand the insurance profession to which the data is being applied?

• A. Mathematics and statistics
• B. Data science
• C. Domain knowledge
• D. Computer programming

Answer: (C)

Understanding how the insurance business operates is essential when applying data science to insurance. Domain knowledge means knowing how insurance products work, how pricing and underwriting are done, how claims are processed, what factors drive risk, and what regulatory and governance constraints apply. This insight shapes which data are meaningful, which features to use, and how to interpret model results in a way that reflects real-world insurance problems.

While mathematics and statistics provide the techniques and data science offers the overall approach, and programming is a tool to implement solutions, those skills alone don’t ensure the results will be relevant or compliant in an insurance context. Domain knowledge bridges the gap between numbers and meaningful, actionable insights for insurers.
