A data scientist might do the following tasks on a day-to-day basis:

  1. Find patterns and trends in datasets to uncover insights
  2. Create algorithms and data models to forecast outcomes
  3. Use machine learning techniques to improve the quality of data or product offerings
  4. Communicate recommendations to other teams and senior staff
