Even though Y-data is not used and there is no indication of Y-data on the screen in the SD Mode, the calculator still maintains a Y-value (always zero) internally for each X-data.

Because of this, if you perform a statistical calculation operation that involves Y-data (such as Σy) after inputting single-variable data in the SD Mode, the calculator will produce a result without displaying an error.

A Editing Sample Data

You can use the procedures in this section to perform the following STAT editor screen editing operations: replace cell contents, insert a line, insert a cell, delete a cell, and delete all STAT editor screen data.

Replacing the Contents of a Cell

Use the cursor keys to move the cursor to the cell whose contents you want to replace and then input the value or calculation expression you want. After you are finished, press E to register your input.

Inserting a Line1.Move the cursor to the location where you want to insert the line.2.Press z5(STAT)1(Edit)1(Ins Row).

This shifts the line where the cursor is located and everything below it downwards, and inserts a new line.

All of the columns in the newly inserted lines are filled in with the applicable initial default values (X = 0, Y = 0 if applicable, FREQ = 1).

Deleting all STAT Editor Data1.Press z5(STAT)1(Edit)2(Del All).• This causes the “Delete All Data?” confirmation message to appear.

2.To delete all STAT editor data, press E(Yes). To cancel the operation without deleting anything, press J(No).

Inserting a Cell1.Move the cursor to the location where you want to insert the cell.2.Press z5(STAT)1(Edit)3(Ins Cell).

This shifts the cell where the cursor is located and everything below it downwards, and inserts a new cell. The cell at the bottom of the column where the new cell is inserted is deleted automatically.

(Ins Cell)

The inserted cell is filled in with the applicable initial default value (X = 0, Y = 0, or FREQ = 1).

Deleting a Cell1. Move the cursor to the cell you want to delete.
