解説
問 23
Incorrectア
An IT strategist is a senior professional who formulates the overall strategy and utilization policy for information systems based on business strategy. Their role is to align business and IT, and their main work is not analyzing large volumes of data with statistics and machine learning.
Incorrectイ
A system architect is an engineer who designs the structure and composition (architecture) of an information system. Their role is the overall design of hardware and software, which differs from the role of extracting value from data analysis.
Incorrectウ
A system analyst's role is to analyze the target operations to be systemized, compile the requirements, and formulate a systemization concept. Their focus is business analysis, not drawing insights from data using statistics and machine learning.
- エ
正解 The correct answer is “エ Data Scientist.” It refers to a specialist who skillfully uses methods such as statistics and machine learning to analyze large volumes of data and draws out hints and insights that lead to the creation of new services and value. The statements in the question — “statistics and machine learning,” “analyze large volumes of data,” and “extract hints and ideas for creating new services and value” — describe exactly the role of a data scientist and match it.
ここがポイント
- Grasp the definition: a data scientist is a specialist who analyzes large volumes of data with methods such as statistics and machine learning to draw out business value and hints.
- Distinguish it from similar job titles (IT strategist, system architect, system analyst) by their roles, using the keywords (statistics, machine learning, data analysis).
