Single-Variable Statistical Graphs________
•Single-variable statistical graphs are drawn in the SD2 mode ( @ @ Q ) . “ SD2”
appears on the display.
•Bar graphs and normal distribution curves can be produced as single-variable
statistical graphs.
•Function graphs are also possible in the SD2 mode, so graphs of theoretical values
and graphs of actual values can be overdrawn.
*Abs and
3
\T "cannot be used in the SD2 mode.
•The maximum number of data items is identical to the number of memories.
You can expand memories up to a maximum of 19. If you specify a number greater
than 19, the unit automatically sets the number of memories as 19.
•Graphs are drawn with the ^-coordinate as the data range and the ^-coordinate
as the number of items (frequency) of each data.
•The m key is used for data input.
•The (¡¡9 key is used for data correction.

*Data input method in step 5 is the same as that for standard deviation calcula­
tions (see page 67).
