data scientist
Big information analyst
A data scientist analyzes large datasets to extract insights and inform decisions.
The role combines statistics, programming, and domain expertise to find patterns in data that humans alone couldn't detect.
Our data scientist built a model predicting customer churn.
The title emerged in the 2010s as companies accumulated more data than traditional analysts could handle.
