Week 5

This week we will be talking about probability.  This marks the transition in the course from descriptive statistics to inferential statistics.   In the first three chapters we studied descriptive statistics, methods that help us describe, organize, and display data in meaningful way.  We’ll use the probability concepts in this chapter for the rest of the course where we’ll focus on inferential statistics, which involves using sample data and probability models to draw conclusions about a larger population. 

These problems can be tricky!  Many students consider this chapter to be somewhat difficult, so please make sure that you give yourself enough time for the online homework. 

The discussion board resumes this week.  Please post three times over three different days to receive the maximum discussion board credit.
