List Function

A list is a storage place for multiple data items.

This calculator lets you store up to 20 lists in a single file, and

you can store up to six files in memory. Stored lists can be used

in arithmetic and statistical calculations, and for graphing.

3-1 Inputting and Editing a List

Enter the STAT Mode from the Main Menu to input data into a list and to manipulate list data.

uTo input values one-by-one

Use the cursor keys to move the highlighting to the list name or cell you want to select.

The screen automatically scrolls when the highlighting is located at either edge of the

screen.

The following example is performed starting with the highlighting located at Cell 1 of List 1.

1. Input a value and press wto store it in the list.

•The highlighting automatically moves down to the

next cell for input.

2. Input the value 4 in the second cell, and then input the result of 2 + 3 in the next cell.

Inputting and Editing a List

#You can also input the result of an expres-

sion or a complex number into a cell.

#You can input value for up to 255 cells in a single

list.

19990401

uTo batch input a series of values

1. Use the cursor keys to move the highlighting to another list.

2. Press !*( { ), and then input the values you want, pressing ,between each one.

Press !/( } ) after inputting the final value.

!*( { )g,h,i!/( } )

3. Press wto store all of the values in your list.

You can also use list names inside of a mathematical expression to input values into another

cell. The following example shows how to add the values in each row in List 1 and List 2, and

input the result into List 3.

1. Use the cursor keys to move the highlighting to the name of the list where you want the

calculation results to be input.

2. Press Kand input the expression.

Inputting and Editing a List

#You can also use !b(List) in place of

K1(LIST)b(List).

# Remember that a comma separates values, so

you should not input a comma after the final

value of the set you are inputting.

Right: {34, 53, 78}

Wrong: {34, 53, 78,}

kEditing List Values

uTo change a cell value

Use dor eto move the highlighting to the cell whose value you want to change. Input the

new value and press wto replace the old data with the new one.

uTo edit the contents of a cell

1. Use the cursor keys to move the highlighting to the cell whose contents you want to

edit.

2. Press 6(䉯)2(EDIT) to display the contents of the cell at the bottom of the screen.

3. Make any changes in the data you want.

uTo delete a cell

1. Use the cursor keys to move the highlighting to the cell you want to delete.

2. Press 3(DEL) to delete the selected cell and cause everything below it to be shifted

up.

3-1-3

Inputting and Editing a List

# The cell delete operation does not affect cells

in other lists. If the data in the list whose cell

you delete is somehow related to the data in

neighboring lists, deleting a cell can cause

related values to become misaligned.

19990401

uTo delete all cells in a list

Use the following procedure to delete all the data in a list.

1. Use the cursor key to move the highlighting to any cell of the list whose data you want

to delete.

2. Pressing 4(DEL

•

A) causes a confirmation message to appear.

3. Press w(Yes) to delete all the cells in the selected list or i(No) to abort the delete

operation without deleting anything.

uTo insert a new cell

1. Use the cursor keys to move the highlighting to the location where you want to insert

the new cell.

2. Press 5(INS) to insert a new cell, which contains a value of 0, causing everything

below it to be shifted down.

#The cell insert operation does not affect cells in

other lists. If the data in the list where you insert

a cell is somehow related to the data in

neighboring lists, inserting a cell can cause

related values to become misaligned.

19990401

kSorting List Values

You can sort lists into either ascending or descending order. The highlighting can be located

in any cell of the list.

uTo sort a single list

Ascending order

1. While the lists are on the screen, press 6(䉯)1(SORT)b(SortA).

2. The prompt “How Many Lists?: ” appears to ask how many lists you want to sort. Here

we will input 1 to indicate we want to sort only one list.

3. In response to the “Select List List No: ” prompt, input the number of the list you want

to sort.

Descending order

Use the same procedure as that for the ascending order sort. The only difference is that

you should press c(SortD) in place of b(SortA).

uTo sort multiple lists

You can link multiple lists together for a sort so that all of their cells are rearranged in

accordance with the sorting of a base list. The base list is sorted into either ascending order

or descending order, while the cells of the linked lists are arranged so that the relative

relationship of all the rows is maintained.

Ascending order

1. While the lists are on the screen, press 6(䉯)1(SORT)b(SortA).

2. The prompt “How Many Lists?: ” appears to ask how many lists you want to sort. Here

we will sort one base list linked to one other list, so we should input 2.

3. In response to the “Select Base List List No: ” prompt, input the number of the list you

want to sort into ascending order. Here we will specify List 1.

4. In response to the “Select Second List List No:” prompt, input the number of the list

you want to link to the base list. Here we will specify List 2.

Inputting and Editing a List

Descending order

Use the same procedure as that for the ascending order sort. The only difference is that

you should press c(SortD) in place of b(SortA).

#You can specify a value from 1 to 6 as the

number of lists for sorting.

#If you specify a list more than once for a single

sort operation, an error occurs.

An error also occurs if lists specified for sorting

do not have the same number of values (rows).

#Specifying a value of 0 for the number of lists

causes all the lists in the file to be sorted. In

this case you specify a base list on which all

other lists in the file are sorted.

3-2 Manipulating List Data

List data can be used in arithmetic and function calculations. In addition, various list data

manipulation functions makes manipulation of list data quick and easy.

You can use list data manipulation functions in the RUN

•

MAT,STAT,GRPH

•

TBL,EQUA and

PRGM Modes.

kAccessing the List Data Manipulation Function Menu

All of the following examples are performed after entering the RUN

•

MAT Mode.

Press Kand then 1(LIST) to display the list data manipulation menu, which contains the

following items.

•{List}/{Dim}/{Seq}/{Min}/{Max}/{Mean}/{Median}/{Sum}/{Prod}/{Cuml}/{%}/{AA

AList}/

{Augmnt}/{Fill}/{L→Mat}

Note that all closing parentheses at the end of the following operations can be omitted.

uTo count the number of data items in a list [OPTN]-[LIST]-[Dim]

K1(LIST)c(Dim)1(LIST)b(List) <list number 1-20> w

•The number of cells a list contains is its “dimension.”

uTo create a list or matrix by specifying the number of data items

[OPTN]-[LIST]-[Dim]

Use the following procedure to specify the number of data in the assignment statement

and create a list.

<number of data n>aK1(LIST)c(Dim)1(LIST)b(List)

You can view the newly created list by entering

the STAT Mode.

Use the following procedure to specify the number of data rows and columns, and the matrix

name in the assignment statement and create a matrix.

!*({)<number of row m> ,<number of column n> !/(})a
