DISPLAY AND INTERPRET DATA

This unit is about organizing and interpreting data.  Stem-and-leaf plots may be used to order and organize data.  Data can be interpreted by calculating measures of variation and organizing the data into box-and-whiskers plots.  After processing data into an ordered display, predictions may be made based upon the trends of the data.
