Five Number Summary
The five number summary of a set of data lists the minimum, lower quartile, median,
upper quartile and maximum values of a data set. Finding these values for large data sets
can be a tedious process, but fortunately your calculator can calculate them for you.
Organising the input data
The data set should be stored as a single list in your calculator.
You can edit these data lists with $<ô. Use your õ and ö keys to move
between the lists, and the ú and ù keys to move up and down each list. To enter
a piece of data, select the list you wish to enter it into, type the number and press ô.
You can delete single items by highlighting them and pressing *, and you can delete
entire lists by highlighting the top of the list and pressing *.
Keystrokes
Use the ñ to enter standard calculation mode. Enter the statistics menu with the $
key, and select 1_Stats by pressing ?~.
Enter the list which contains the data in question using % followed by ~…Ñ,
then press ô.
The screen you are presented with contains many different statistics concerning your
data set, but the values you are interested in are at the very bottom of the list. Scroll
down to them using the down arrow.
