What data scientists do

Data scientists find patterns and answers in data. They write SQL and Python to gather and clean data, explore it with statistics and visualizations, build predictive models, run experiments and explain results to decision-makers. They work in tech, healthcare, finance, retail, government and nearly every other industry.

Most data scientists have at least a bachelor’s degree in a quantitative field, and many have master’s degrees. Strong programming, statistics and communication skills matter most. It is one of the fastest-growing occupations, and many people enter through data analyst roles.

Typical duties

  • Gather and clean data from many sources
  • Explore data with statistics and visualizations
  • Build predictive and machine learning models
  • Design and analyze experiments
  • Deploy and monitor models
  • Create dashboards and reports
  • Explain findings to stakeholders

Work environment and schedule

Data scientists work in offices or remotely at computers, collaborating with engineers, analysts and business teams.

Schedule: Most work full-time with flexible hours and occasional deadline crunches.

A day in the life

  1. Review dashboard metrics and check on a model running in production.
  2. Write SQL to pull customer data for a churn analysis.
  3. Clean the data and explore patterns in a notebook.
  4. Train and compare machine learning models.
