Guidance


Often, the number of data values is quite large, and the task of organizing the data can take a great deal of time.
To help organize data, the TI-83 calculator can be used. The following examples will show you how to use the
calculator to organize data and find the median for the data values.


Example A


The local police department spent the holiday weekend ticketing drivers who were speeding. 50 locations within the
