Tip:
The DispStat window shows statistical calculation results of the last statistical calculation that was executed using
any ClassPad application (except for eActivity). For example, immediately after a calculation is executed using
"NormPD" command in the Main application, that calculation result is displayed on the DispStat window, even with
the Spreadsheet application. However, note that calculation results produced using a mathematical function, such as
"normPDf(", are not displayed on the DispStat window.
13-4 Cell and List Calculations
Using the Cell Calculation Functions
Spreadsheet application special functions are included on the [Cell-Calculation] submenu of the [Calc] menu.
Selecting a menu item on the [Cell-Calculation] submenu will input the corresponding function into the currently
selected cell. This section provides explanations of the functions and input syntax of the cell calculation
functions.
Function
Description
row
Function: Returns the row number of a specified cell.
Syntax: row(cell)
col
Function: Returns the column number of a specified cell.
Syntax: col(cell)
count
Function: Returns a count of the number of cells in the specified range.
Syntax: count(start cell[:end cell])
cellif
Function: Evaluates an equality or inequality, and returns one of three different expressions
With this function, the equality/inequality can include a string as in the following example:
cellif(A1="Red", 0,1,2).
Syntax: cellif(equation, expression 1, expression 2, expression 3)
1303
For each value in cells A1 through A5, to display "Big" in the neighboring B-column cell for values of 5
and greater, and "Small" for values less than 5
Using the List Calculation Functions
The [Calc] menu functions shown in the table below are also included (with the same name) on the Main
application [Action] - [List] - [Statistics] and [Action] - [List] - [Calculation] submenus.
[Calc] - [List-Statistics] submenu
[Calc] - [List-Calculation] submenu
Selecting a menu item on the [Calc] - [List-Statistics] submenu or [Calc] - [List-Calculation] submenu will input
the corresponding function into the currently selected cell. For information about the syntax and other details
about each function, see "Using the List-Statistics and List-Calculation Submenus" (page 72).
Tip:
When a range of cells on a spreadsheet is specified as the arguments of these functions,
the cells are regarded of a single list of data even if the range extends over multiple
columns. For example, in the case of the nearby screenshot (where the range A1:B3 is
selected), the data is treated as the following list data: {1,3,5,2,4,6}.
1304
To determine the mean of the values in the block whose upper left corner is located at A1 and whose
lower right corner is located at C3, and input the result in cell C5
1305
When Column A is data and Column B is frequency, to totalize the data input
in A1 through B3 in the nearby screenshot and input the total into cell B5
based on whether the equality/inequality is true (expression 1), false (expression 2),
or inconclusive (expression 3).
cellif(inequality, expression 1, expression 2, expression 3)
min, max, mean, median, mode, Q
sum, prod, cuml, Alist, percent, polyEval, sequence, sumSeq
, Q
, percentile, stdDev, variance
