Discussion Topic

We probably all agree we live in a highly technical world, and it’s growing.   In fact, big data has become a part of everyday life.  Ever thought of how each click of the mouse or your words on social media are tracked?  Companies gather data about everything you do on your phone, computer, TV, Alexa, Amazon Echo, Google Home Mini, etc.  In fact, the number of bytes used and required to gather information have grown astronomically over the past 20 years.   All this data gathering creates problems for statistics.

As you read Chapter 7, pay particular attention to the information about Big Data on pages 356 through 358, watch the TED Ed and TED videos below, then address the questions.

TED Ed – There is a mind-boggling amount of data floating around our society. Physicists at CERN have been pondering how to store and share their ever more massive data for decades – stimulating globalization of the internet along the way, whilst ‘solving’ their big data problem. Tim Smith plots CERN’s involvement with big data from fifty years ago to today.

TED – Big Data is Better Data

Self-driving cars were just the start. What’s the future of big data-driven technology and design? In a thrilling science talk, Kenneth Cukier looks at what’s next for machine learning — and human knowledge.

Big Data is Better Data (Links to an external site.), by Kenneth Cukier

TED Ed – Statistics are persuasive. So much so that people, organizations, and whole countries base some of their most important decisions on organized data. But any set of statistics might have something lurking inside it that can turn the results completely upside down.
