Features

Output Tables
33 Tables, many with subtables, report all aspects of
the analysis: Person and item scores, measures,
standard errors, quality-control fit statistics, summary
statistics, reliabilities, subtotals, individual reporting,
differential item functioning, rating scale functioning,
score-to-measure conversion, Guttman scalograms,
paired-comparisons, and more

Output Files & Excel Plots
16 output files for exporting measures, standard
errors, quality-control fit statistics as EXCEL, SPSS
or text files for input to other software. Immediate
display, if desired. Here is a “Bond & Fox”-style
Bubble Chart automatically displayed by Excel.

Differential Item Functioning
Detailed Tables and Plots of uniform and non-uniform
DIF size and significance. Also Mantel-Haenszel and
Mantel statistics. Differential Person functioning and
Differential Person-group vs. Item-group functioning.

Principal components analysis of
residuals for multidimensionality
of persons or items. Reporting of unexpected
observations helps identify problems in the data or
instrument conceptualization.
Also: Multiple concurrent analyses. Batch mode
operation. Frequent enhancements (free for a year).
Training seminars. Need an extra feature? Tell us!

Help Feature
Full user documentation and many examples in the
Help file of the 140 user options. Detailed
descriptions of every output table. 50 technical
“special topics” address operational, analytical and
interpretive issues. Free downloadable PDF of
Program Manual.

What is being measured?
Construct validity: defining the latent variable
items ordered: from frequent to rare, from easy to
hard, from loved to hated. Item anchoring and
weighting, tabular and graphical output. Estimates
of item discrimination and guessability.

(ICCs) with confidence bands for individual items
or all items which share the same scale structure.
Category probability curves. Test, item and category
information functions. Test characteristic curve.
Detailed statistics for each category: counts,
measures, and quality-control fit statistics. Re-order
and collapse categories. Remedy keying errors and
reversed items. Multiple-choice scoring keys.
Multiple ICCs on one graph.

Overview

Winsteps constructs Rasch measures from simple rectangular data sets, usually of persons and items. After initial familiarization, it is straightforward to use in combination with other software. Item types that can be combined in one analysis include dichotomous, multiple-choice, and multiple rating-scale and partial credit items. Paired comparisons and rank-order data can also be analyzed. Missing data is no problem. Winsteps is designed as a tool that facilitates exploration and communication. The structure of the items and persons can be examined in depth. Unexpected data points are identified and reported in numerous ways. Powerful diagnosis of multidimensionality through principal components analysis of residuals detects and quantifies substructures in the data. The working of rating scales can be examined thoroughly, and rating scales can be recoded and items regrouped to share rating scales as desired. Measures can be fixed (anchored) at pre-set values. Winsteps is intended for practitioners who must make practical and quick decisions along the path to constructing effective tests, and who must then communicate their results usefully to end users. The developers of Winsteps use the program daily in their own work, and are continually adding new features as a result of their own experience and feedback from users. Typical applications include educational tests, psychological assessments, attitude surveys, patient performance protocols, and calibrating adaptive-test item banks. Winsteps can process up to 1,000,000 persons, 30,000 items, and each item can have a rating scale of up to 255 categories. Training seminars are held regularly. Student/evaluation/demo versions of Winsteps can be downloaded free from www.winsteps.com/ministep.htm. Its DOS-based predecessor, Bigsteps, with a capacity of 20,000 persons and 1,000 items, can also be downloaded free from www.winsteps.com/bigsteps.htm.
