Data Scientist

Summary

A Data Scientist is responsible for collecting and analyzing vast amounts of data in order to solve business-related problems. They’ll clean the data up and transform it into a more usable format, then look for patterns and trends in the data that will help the business. In order to do so a data scientist will need to be familiar with programming languages such as SAS, R, and Python, have a solid grasp of statistics, and collaborate with both IT and business sides of a company.

  • Programming (SAS, R, Python)
  • Statistics
  • Machine learning
  • Linear algebra and calculus
  • Data visualization
  • Communication
  • Data Wrangling
  • Software Engineering
  • Data Intuition

Data scientists have some of the steepest education requirements of all IT occupations. Most positions require an advanced degree, such as a Master’s or PhD in computer science, math and statistics, economics, engineering, or a related field. However, some companies will accept data scientists with a Bachelor’s of Science degree in the above fields.

  • Data engineer
  • Business Intelligence Developer
  • Business analyst
