User manual - Modifications Made to ALGEBRA 2.0 by STAT2

· The coordinates do not appear if [Off] is specified for the [Coord] item of the [SETUP] screen.

· The Y-CAL function can also be used with a graph drawn by using DefG feature.

uRegression Formula Copy Function from a Regression Calculation Result

Screen

In addition to the existing regression formula copy function that lets you copy the regression

calculation result screen after drawing a statistical graph (such as Scatter Plot), STAT2 also

adds a function that lets you copy the regression formula obtained as the result of a regression

calculation. This type of copy operation is performed by pressing 6(COPY).

k Tests, Confidence Interval, and Distribution Calculations

STAT2 adds functions for performing tests, confidence interval, and distribution calculations.

This manual fully describes each of these calculations in separate chapters: Chapter 2 Tests,

Chapter 3 Confidence Interval, and Chapter 4 Distribution.

uParameter Settings

The following describes the two methods you can use to make parameter settings for test,

confidence interval, and distribution calculations.

• Selection

With this method, you press the function key that corresponds to the setting you want to

select from the function menu.

• Value Input

With this method, you directly input the parameter value you want to input. In this case,

nothing appears in the function menu.

· Pressing i returns to the list input screen, with the cursor in the same position it was at

before you started the parameter setting procedure.

· Pressing ! i (QUIT) returns to the top of list input screen.

· Pressing w without pressing 1 (CALC) under “Execute” item advances to calculation ex-

ecution. To return to the parameter setting screen, press i, A, or w.

uCommon Functions

• The symbol “

■

” appears in the upper right corner of the screen while execution of a calcula-

tion is being performed and while a graph is being drawn. Pressing A during this time

terminates the ongoing calculation or draw operation (AC Break).

• Pressing i or w while a calculation result or graph is on the display returns to the param-

eter setting screen. Pressing ! i (QUIT) returns to the top of list input screen.
