The Rise of the Data Scientist

Jonathan Cornelissen tells us about DataCamp, the need for data scientists, and how to become one yourself. We also learn about some popular languages and libraries for analyzing data.

Here's what to listen for:

• 05:26 Does DataCamp help establish a theoretical background?
• 06:21 Do only big companies need data science?
• 07:16 What is big data?
• 07:58 Can the term big data be used interchangeably with data science?
• 09:08 Do you need a “billion dollar budget” to build a data science team? What kind of people do I need to build that kind of team?

• 25:30 Is R still evolving as a language?
• 25:58 Is there anything people should try to learn before trying to tackle R as a language?
• 26:52 Why learn a language like R?
• 28:27 Does R allow you the ability to communicate the insights that you’re getting from the data that you’ve analyzed to build a narrative to help the non-technical people on your team?
• 29:19 Is visualizing the data that we get back important to our understanding of that data? Why?
• 29:57 Does DataCamp help people visualize data?
