9/6/12

We spent more time today working with the mean, mode, 5 number summary, box plots, and histograms.  We also learned about range--the difference between the max and min values (max-min) and the IQR--Interquartile range--difference between Q3 and Q1 (Q3-Q1).  We did several examples including one about hte food at McDonalds--drawing three conclusions at the end of our analysis.  Tomorrow we will be working on a stat project in the media center (handout for the project) (sample project).  These will be due on Weds of next week.  NO LATE PROJECTS WILL BE ACCEPTED!!
