What Is a Data Scientist?
Data are being acquired faster than ever before and are being used to make decisions in business, healthcare, science, and government policy. Yet amassing huge quantities of data and applying fancy statistical analysis often lead to meaningless, if not misleading, results.
Powerful computers and sophisticated statistical algorithms are able to process data to find patterns and trends, but they cannot explain the data and predict in a way that makes sense. Data scientists, on the other hand, are able to extract insights from the data to tell a story, to provide solutions.
Since the connection between the data and the decision-maker's problem is not obvious, the data scientist will help to understand and clarify it. The data scientist has the technical expertise and theoretical understanding to infer valid conclusions, find clear and effective ways to communicate the findings to both a technical and non-technical audience, understands the ethics and responsibility of handling data, is a creative problem solver, and is inherently curious about what patterns of data can reveal. The data scientist makes sense of data.
