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.
