Enter the data into a list (spreadsheet).
Label column A to be "data" (or any name you choose).
Find the Mean and Median:
Method 1: (fast and easy)
Go to a Calculator Page .
Press and choose #1 Calculator. Hit ENTER.
Press (Catalog) , then M , and choose mean( or median(.
These commands can also be used with direct entries, such as:
mean() gives an answer of 4.5
(the french curly braces are under the catalog key template)
mean(, ) gives an answer of 13/3.
The values are actually 3, 4, 4, 5, 5, 5, where the second set indicates the number of entries of each corresponding value in the preceeding set..
Syntax: mean(List[, freqList[ )
If each data entry is to be considered only once, the freqList[ is one and need not be entered.
In this example, the decimal approximation was achieved using CTRL and .
Syntax: median(List[ )
List[ will be the name of the list where the data resides, or you may enter the data directly, as seen at the left in reference to mean.
Find the Mean and Median:
Method 2: (a bit more sophisticated)
From the List & Spreadsheet Page , press
, #4 Statistics, #1 Stat Calculations , and choose #1 One-Variable Statistics.
The choice "Open Variable Statistics" yields the following results back to the spreadsheet columns. One column will "label" these values, while the following column will contain the actual results.
