Data Science with Open Data Quiz Answers – Cognitive Class

Get Data Science with Open Data Quiz Answers

The National Energy Board of Canada?? has established Data and Information Management as a focus area for the future. The objectives are to increase capacity in data analytics, experimentation culture and evidence-based decision making withing their organization but more broadly in the communities they serve.

One pillar of this strategy is to develop open data science training content, developed using open data. Success is predicated on all of us having a common understanding of data terminology, tools and techniques, so nothing is “lost in translation.” This course is open to public servants in Canada and to the general public.

Data experts are encouraged to participate, no programming or IT experience are required and, participants from non-technical backgrounds are encouraged to take this short course. Happy learning!

Module 1 – What is Data Science?

Question: What is Data Science?
