is the Winsteps "Adjutant's Bugle Call" - play this when you are summoning the data in preparation for constructing measures!

Scaling calculator

is designed to help you linearly rescale your measures in the way most meaningful for your audience:



Under Current measure: enter two measures from your current analysis.

Under Desired measure: enter the values with which you want them to be reported.

Under Decimals: enter the number of decimal places for the measure Tables, Udecimals=.

Press Compute New to calculate the revised values of Uimean= and Uscale=.

The current values of Uimean= and Uscale= are displayed and also the revised New values. The New values can be altered if you wish.

Press Specify New to action the New values. Or the values can be copied (Ctrl+c) and pasted into your Winsteps control file.


Example: We want the mean and S.D. of our sample to be 0 and 1.


Current Table 3.1


|           RAW                        

|          SCORE     COUNT     MEASURE 


| MEAN      31.7      25.0         .97 

| S.D.       8.7        .0        1.35 


The current mean = .97

The current mean + 1 S.D. = .97 +1.35


The desired mean = 0

The desired mean + 1 S.D. = 0+1



New Table 3.1


|           RAW                        

|          SCORE     COUNT     MEASURE 


| MEAN      31.7      25.0         .00 

| S.D.       8.7        .0        1.00 


Example: If I use IAFILE= and SAFILE= for some items, how do I rescale the analysis to set the reported person measure range as 0-100?

1. Do your analysis with IAFILE= and SAFILE=. USCALE= in this analysis is the value of USCALE= in the analysis that output the SAFILE=

2. Output Tables menu: Table 20.1. Identify the measure you want tobe 0, and the measure you want to be 100

3. Help menu: Scaling calculator
"Current Measure:" are the two measures from Table 20.1
"Desired Measure:" are the two measures you want
Click on "Compute New:" write down the value of Uscale= for your next analysis
Click on "Specifiy New"

4. Output Tables menu: Table 20.1. The range should be 0-100.

5. Output IFILE=if.txt, SFILE=sf.txt

6. Do the analysis again: IAFILE=if.txt, SAFILE=sf.txt and USCALE= the value of Uscale= from 3.

7. Output Tables menu: Table 20.1. The range should be 0-100.
