Scalar Module

Invoking the Scalar Module

Clicking the Scalar module command with the left mouse button will open the folded scalar module

Clicking the Scalar module with the right mouse button, or clicking the Unfold command in the lower left corner of the folded scalar module

will open the scalar module as

Store Statistics in the Scalar Module

Enter the first two Bivariate prototypes, click ( Analysis I, Correlation ), mark the X and Y variables

and click on the Accept command.

Clicking on the Correlation, Determination, and Alienation commands will send their values to the Scalar module

where there they will be saved for future use; as e.g., for the writing the research report. Note that you can drag values stored in the scalar module
to many other applications.

Evaluate Variance Components of the Multiple Regression Analysis

Select ( Designs, Regression Analysis, Multiple Regression Analysis with Two Predictor Variables ) and click on the Accept command.
Select ( Analysis I, Multiple Regression Analysis ), mark the X1, X2 Predictor Variables, the Y Criterion Variable, and click on the  Accept command.

Select the Descriptive Statistics, highlight the Standardize Variance command,

and under the Select the Standardizing Variable heading mark the predictor variable Y. Click on the Accept command.

Select the ( Transfers, Descriptor-Scalars ) commands and mark the Standard Variance command.

Click on the ( Accept, Select All, Accept ) commands. Drag the Y', +,  and Y^ values to the calculator display and click the Equals command. Drag the result ( 1 ) to the Value cell, click on the Variable cell located above, Name the Variable Y'+Y^, and click the Enter command. Click on the Index cell and the ~sigma command.

Following the analogous procedures, you can demonstrate the additivity of other regression components using the orthogonal predictor variables.

The scalar module has many other functions which you may discover while working with the Visual Statistics Studio.
