IPA IP 2024 Question 26
A question IPA Japan published in 令和6年度 ITパスポート試験 公開問題 問26, translated into English. ITPEC is based on the same exams.
Which of the following is the most appropriate description concerning the role of a data scientist?
Explanation
Analysing big data with machine learning and statistics to gain new insights for the business — that is what a data scientist is for.
A data scientist combines three kinds of skill: statistics and machine learning to analyse data, IT skills to handle large data sets, and business understanding to ask the right questions and turn the results into action. The job is to find patterns, causes and predictions in big data that the business can use, for example in demand forecasting, pricing or customer analysis.
Answer (a)
Why not others:
- •(b) — building and running the high-performance database platform is the work of a data engineer or infrastructure engineer, who prepares the data a data scientist then analyses
- •(c) — investigating how data is actually handled and managed on site in order to assess the risks of information systems is the work of a system auditor or a risk assessor
- •(d) — supporting the planning, design, development and operation of secure systems with cybersecurity expertise is the role of a security specialist (in Japan, the national Registered Information Security Specialist)
Key rule: A data scientist turns data into business insight through analysis; building the data platform, auditing and security are other specialists' roles.
