9 Types of Data Scientists

This is an excerpt from the article published by Vincent Granville which can be found at http://www.datasciencecentral.com/profiles/blogs/six-categories-of-data-scientists

We are now at 9 categories after a few updates. Just like there are a few categories of statisticians (biostatisticians, statisticians, econometricians, operations research specialists, actuaries) or business analysts (marketing-oriented, product-oriented, finance-oriented, etc.) we have different categories of data scientists.

 

Categories of data scientists

  • Those strong in statistics: they sometimes develop new statistical theories for big data, that even traditional statisticians are not aware of. They are expert in statistical modeling, experimental design, sampling, clustering, data reduction, confidence intervals, testing, modeling, predictive modeling and other related techniques.
  • Those strong in mathematics: NSA (national security agency) or defense/military people working on big data, astronomers, and operations research people doing analytic business optimization (inventory management and forecasting, pricing optimization, supply chain, quality control, yield optimization) as they collect, analyse and extract value out of data.
  • Those strong in data engineering, Hadoop, database/memory/file systems optimization and architecture, API’s, Analytics as a Service, optimization of data flows, data plumbing.
  • Those strong in machine learning / computer science (algorithms, computational complexity)
  • Those strong in business, ROI optimization, decision sciences, involved in some of the tasks traditionally performed by business analysts in bigger companies (dashboards design, metric mix selection and metric definitions, ROI optimization, high-level database design)
  • Those strong in production code development, software engineering (they know a few programming languages)
  • Those strong in visualization
  • Those strong in GIS, spatial data, data modeled by graphs, graph databases
  • Those strong in a few of the above. After 20 years of experience across many industries, big and small companies (and lots of training), I’m strong both in stats, machine learning, business, mathematics and more than just familiar with visualization and data engineering. This could happen to you as well over time, as you build experience. I mention this because so many people still think that it is not possible to develop a strong knowledge base across multiple domains that are traditionally perceived as separated (the silo mentality). Indeed, that’s the very reason why data science was created.

Most of them are familiar or expert in big data.

Interesting! What needs be be added/deleted now that this post is a few users old? Can we start defining by domain, for example IT Data Scientist, Marketing Data Scientist and so on?
