Score and measure file output

Top Up Down  A A

From the Output Files menu as Score and measure file output. This enables you to control the Score and measure file. Score and measure output files simplify the transfer of measures  to other computer software. you may specify a file name that will be used to construct files to hold the numeric results presented in Facets measure tables. Also produced by Scorefile=.

 

The measures for each facet are written to a separate file, whose name is that specified, with the facet number appended. E.g., if Scorefile=Results, then the measures for facet 1 are written to Results.1, for facet 2 to Results.2 etc.

For Excel-formatted output files, the scores and measures for the element of each facet are written to a separate worksheet within the same workbook.

For SPSS-formatted output files, the scores and measures for the elements of all facets are written to one SPSS .sav file, which includes facet number as a variable.

Select Facets: specifies which the facets for which the elements are to be reported.

 

Select file format:

Include column headings - usually headings are not wanted when a score file is to be imported into a database.

 

Omit unobserved elements from output - reports all elements specified in Labels=. Otherwise only elements active in this analysis are reported.

 

Labels between quotation marks - useful if labels contain blanks. The quotation mark character can be specified.

 

Tab-separated fields - best field format for Excel

 

Character-separated fields - best field format for some database programs.

 

Fixed-length fields - easiest field format to read by eye.

 

The Buttons are described in Output Dialog box.

 

Score fields to output: to select which fields to include in the score file.

 

 

Check the fields to be output (see score file). Then click on OK.

 

Example: Write out score files for each facet in fixed field format:

Score file= kct

 

This puts the measures for facet 1 in file "kct.1.txt", for facet 2 in "kct.2.txt", etc. The results depend on the score file field selection, but can be:
