  4. What is Data Science?

  5. One definition, Cassie Kozyrkov Data science is the discipline

    of making data useful
  6. Classic data science venn diagram

  7. Our (slightly updated) version

  8. Programming: What you need to know OR

  9. Mathematics & statistics 1. What techniques exists • I need

    to group customers together -> I should try clustering 2. How to apply them • How to do a k-means clustering in R/Python 3. How to choose which to try • What clustering method will work best?
  10. How can we split our customers into different groups to

    market to? How can we run a clustering algorithm to segment customer data? Business question Data science question A k-means clustering found 3 distinct groups Data science answer Business answer Here are 3 types of customers: new, high spending, commercial Domain knowledge - Renee Teate, @BecomingDataSci Skills: • Communication • Empathy • Understanding your data (where it lives, built-in assumptions, edge cases)
  11. How Do I Become a Data Scientist?

  12. “Fake data scientists”

  13. “Fake data scientists”

  14. “Must know” lists

  15. “Must know” lists

  16. You don’t need to know everything

  17. How to find a data science job Create a portfolio

    Expand your network Find the right jobs
  18. Creating a Portfolio

  19. What is a portfolio? A public body of work that

    illustrates your data science skills
  20. How?

  21. Dataset -> Question

  22. Dataset -> Question

  23. Question -> Dataset

  24. Tip 1: Include visualizations

  25. Tip 2: choose a topic you’re excited about

  26. Tip 3: Limit your scope

  27. Making progress Inspired by Less valuable More valuable Idea

    Getting data Cleaning Exploratory Final result Modeling Less valuable More valuable Work only on your computer Work online (GitHub, Blog, Kaggle) How I used to think about analyses How I think about analyses now
  28. The full process

  29. Put it on GitHub

  30. Where? ➔ Easy & quick to set up ➔ Organic

    traffic (medium) ➔ Less customizability/control
  31. Where? ➔ Complete control ➔ Always free ➔ Little longer

    to set-up ➔ May get stuck debugging issues
  32. Explain your analysis

  33. Teach a concept

  34. Share your experience

  35. Give advice

  36. Expanding your Network

  37. How people get data science jobs

  38. Meetups – search on

  39. Twitter

  40. Ask for help (use hashtags)

  41. Live tweet talks

  42. Share your work

  43. Share other people’s work

  44. Reaching out • Mentions their work • Offers a topic

    • Suggests a specific time (that’s limited)
  45. Reaching out Check out by Angela Bassa

  46. Reaching out

  47. Finding the right job

  48. Let go of the “data scientist” title “Think about how

    attached you are to the data scientist title. If you decide to not concern yourself with what you’re called and to instead focus on the work that you’re doing, you’ll have a lot more flexibility to find jobs.” - Jesse Mostipak, Community Advocate at Kaggle, Chapter 5
  49. Figure out your specialty

  50. You don’t need to meet all of the “requirements”

  51. Consider the type of company matters Criteria Massive tech Retailer

    Startup Mid tech Government Contractor Bureaucracy Freedom Salary Job security Chances to learn Chapter 2, How data science works at different companies
  52. Conclusion

  53. Take-away points • You don’t need to know everything •

    There’s no such thing as a “fake data scientist” • Let go of the “data scientist” title • Focus on: • Creating a portfolio • Expanding your network • Finding the right job
