Surveys, Testing, and Measurement softwares

CCOUNT -- a package for market research data cleaning, manipulation, cross tabulation and data analysis. Similar to, and uses the same syntax as, SPSS-MR "Quantum", a well known commercial package for processing market research data. Available for Windows, Linux, and SunOS. C++ source code also available, under the GNU General Public Licerse.

ProtoGenie -- a free extensible web-based environment for research design and data collection for surveys, experiments, clinical trials, time series, cognitive and vision research, and methods courses. Lets you specify groups and define measurement and treatment events and their sequencing. The goal is to let users move smoothly from research design and data collection to interim and final statistical analysis.

GGUM2004 (Item Response Theory Models for Unfolding) -- a Windows-based program that estimates parameters in the generalized graded unfolding model (GGUM; Roberts, Donoghue, & Laughlin, 2000). Has a user-friendly interface to prepare command files, run the core estimation program, and display results. Allows different questionnaire items to have varying numbers of response categories (useful when sparse responses require recoding into fewer response categories. Handles sporadically missing responses. Provides item fit statistics and diagnostic graphics of performance.

Rasch Measurement Software -- deals with the various nuances of constructing optimal rating scales from a number of (usually) dichotomous measurements, such as responses to questions in a survey or test. Several free student/demo software packages are available. These may be freely downloaded, used, and distributed, and they do not expire. They are:

• BIGSTEPS -- a DOS-based precursor to the Windows-based WINSTEPS Rasch measurements program.
• MINISTEP -- a free evaluation/student version of WINSTEPS. It has complete WINSTEPS functionality, but is limited to 25 items and 100 persons (cases).
• MINIFAC -- a free evaluation/student version of FACETS (Many-Facet Rasch Analysis). Contains all features except limited to 2,000 data points (responses).

Q-Method -- a statistical program for analyzing data from the Q-Sort Technique. Enter data (Q-Sorts) the way they are collected, i.e. as 'piles' of statement numbers. It computes intercorrelations among Q-Sorts, which are then factor-analysed with the Centroid (or, alternatively, PCA) method. Resulting factors can be rotated either analytically (Varimax), or judgmentally with the help of two-dimensional plots. Finally, after selecting the relevant factors and 'flagging' the entries that define the factors, the analysis step produces an extensive report with a variety of tables on factor loadings, statement factor scores, discriminating statements for each of the factors as well as consensus statements across factors, etc.

AnSWR -- Analysis Software for Word-based Records -- a free software system from the C.D.C. for coordinating and conducting large-scale, team-based analysis projects that integrate qualitative and quantitative techniques (for Windows).

ez-text -- a software program from the C.D.C. developed to assist researchers create, manage, and analyze semi-structured qualitative databases.

CSPro (Census and Survey Processing System) -- a public-domain software package for entering, tabulating and mapping census and survey data.

IMPS (Integrated Microcomputer Processing System) -- performs the major tasks in survey and census data processing: data entry, data editing, tabulation, data dissemination, statistical analysis and data capture control. (from CDC)

WebQ -- a set of HTML files for performing Q-Sorts online and collecting the data for subsequent analysis.

Stats -- Windows program for several commonly-needed statistical functions for marketing researchers: random numbers;sample sizes needed for surveys; mean, standard deviation, standard error and range for keyboard-entered data; standard error of a proportion; significance testing between two percentages from independent samples; significance between two percentages from dependent samples; significance testing between two averages from independent samples; contingency table analysis (i.e., Chi-Square)

SABRE -- for the statistical analysis of multi-process random effect response data. Responses can be binary, ordinal, count and linear recurrent events; response sequences can be of different types. Such multi-process data is common in many research areas, e.g. the analysis of work and life histories. Sabre has been used intensively on many longitudinal datasets surveys either with recurrent information collected over time or with a clustered sampling scheme. 

POSDEM -- Uses simulation techniques to analyze and compare alternate sampling strategies for surveys. Performs power / sample size / precision analyses for different sampling methods: systematic, stratified, random, etc. Windows versions available in Spanish and English.

WISC-III Profile Calculator for Macintosh and Windows -- uses generalized distance method to determine if the subtest profile of a single case is multivariately unusual or common in comparison to subtest clusters found in the WISC-III standardization sample. (Mac, 360K; Win anticipated in September)

DEMETRA -- user-friendly interface to TRAMO/SEATS and X-12-ARIMA .

Sociological Insights -- displays statistical information in an easy-to-use format, designed for teaching quantitative sociological reasoning. It uses aggregate data from the 50 U.S. states to teach the principles of distribution, correlation, and regression. It uses questionnaire data from the 2000 and 1994 General Social Surveys to teach distribution and cross-tabulation. The States module has 289 variables in all. The Survey module displays 249 variables from the 2000 GSS, plus (as a separate data set) 113 variables from the 1994 GSS.

ConTEST -- a decision support system for assembly of educational and psychological tests from item banks.

MUDFOLD (Multiple UniDimensional unFOLDing) -- for analyzing proximity data (e.g., attitudes, preferences, or choices) with the Coombsian unfolding model.

WINMIRA -- Latent Class Analysis (LCA), the Rasch model (RM), and the Mixed Rasch model (MRM) and Hybrid models (HYBRID).

T-Rasch -- exact or non-parametric tests for the Rasch model.

LPCM-WIN -- a menu-driven program to apply ‘Linear Partial Credit Models’ in item analysis and measurement of change.

Kwalitan -- for analysis of qualitative data, such as protocols of interviews, articles, and annual reports.

StatPac Survey Software -- to design andimplement surveys, and to acquire, manage and analyze data from surveys. Supports multiply data types and question formats, multi-language spell-checking, large files (2,000 variables & 10,000,000 cases, basic statistics (crosstab & banner tables) & graphics, automatic coding of text responses, and data import / export capabilities. Optional Web Survey Module and Advanced Statistics Module (curve fitting, multiple regression, logistic regression, factor, analysis of variance, discriminant function, cluster, and canonical correlation). A demo version is available (limited to 35 cases).

NewMDSX -- software for Multidimensional Scaling (MDS), a term that refers to a family of models where the structure in a set of data is represented graphically by the relationships between a set of points in a space. MDS can be used on a variety of data, using different models and allowing different assumptions about the level of measurement. This site offers a free month trial of the Windows version; a completely free copy of constituent programs, notes, documentation, test Input& Output in MS-DOS; a not-for-profit full Windows copy priced at cost; and a site with a range of data, cross-reference, & information.

GLIMMIX -- a powerful approach to segmentation based on latent class models. Analysis of brand choice, purchase frequency and preference data.

CORWIN -- a program for correspondence analysis, which decomposes relations in a two-way table.

Form Artist -- lets you design and create online forms for data collection via the Web. Forms and surveys run on any web server (Microsoft, Unix, Linux ), and work with all browsers (no plugins required. WYSIWYG interface gives complete control over the appearance of forms (any shape, size, number of pages, color scheme). Create multi-page forms on the same web page without reloading.. Supports the usual data entry fields (text, numbers, lists, checkboxes etc.), also unique objects such as picture grids and emoticons. Can fill in forms online or offline. Completed data can then be sent back via email or by file. Free evaluation version available.

AssiStat -- a Windows-based package of calculations and analyses useful in educational and psychological research, practice, and in measurement and statistics courses. Designed as a complement to typical statistical packages rather than as a primary analysis tool, it picks up where primary analysis packages usually fall short--in performing secondary analyses like correction of correlations for restriction in range or less-than-perfect reliability, and other specialized analyses and calculations usually not available in standard packages without special programming. Free demo available.
