21. Are there jobs for Data Scientists?
“The fastest-growing roles
are Data Scientists and
Advanced Analysts, which
are projected to see demand
spike by 28% by 2020.
Employers are willing to pay
premium salaries for
professionals with expertise
in these areas as well.”

23. Do I need a Data Science
degree to do Data Science?
• Technically no……many people currently are “data scientists” with
backgrounds in quantitative degrees that are not data science
– Some with statistics, some with computer science, some with a
combination
– Some with other quantitative degrees
• Advantages of the DS major
– Puts you on the “fast track” to becoming a Data Scientist
– Ensures that you will know the fundamentals of both
• Computing
• Statistics
– Provides you with skills that are likely to have lasting value (as
technology changes)

24. What are other degree options?
• Computer Science with a Statistics minor?
– More classes in “systems” aspects of computer science
– Fewer classes in statistics
– No capstone data science project class
• Another degree like Math or Economics with a Statistics minor?
– Far fewer classes in computer science
– Fewer classes in statistics
– No capstone data science project class
• Statistics undergraduate degree (e.g., at another UC)?
– More classes in mathematics and statistics
– Far fewer classes in computer science
– No capstone data science project class

25. A sample of internship requirements
(from a local firm)
