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
state were targeted as being ideal spots for drivers to exceed the posted speed limit. The number of tickets issued
during the weekend in each of the locations is shown in the following table. What is the median number of speeding
tickets issued? Use your TI calculator to find the answer.
