1 A Web-Based Tool for Gathering Ordinal Rankings
Elizabeth Arnott David Allbritton DePaul University

2 Introduction Ordinal rankings are used widely in many areas:
Psychology Education Business Across areas the rating task itself is relatively standard

3 The Problem Standard procedural methodology for gathering ordinal rankings does not exist Ratings often used as a subordinate tool Poorly defined methodology may lead to inconsistencies (Madden et al., 1965; 1964)

4 Benefits of a Web Interface
Convenient use Information stored in a straightforward manner Minimizes participant error Allows for standard program to be used by any experimenter with web access

5 Perl Script Processes Input Files
Text files (one sentence per line) Groups of items (stories) separated by a blank line Generates XHTML Files for Data Collection Forms linked by a “Submit” button

6 Using the Interface Groups of items to be ordered on a single page
Instructions to order from first to last JavaScript Clicking items with the mouse assigns a corresponding number in a text box Participant can “Submit” or “Reset” when finished

7 Data Collection Perl CGI scripts receive data Data storage:
Text file of comma separated values Storage in a database is also possible Additional Text File Stores story and sentence numbers Facilitates matching

8 Recording the Data Format of text file is minimal:
One line per rating for each participant Fields include: Experiment name Group number Item number Rating

9 Limitations and Future Directions
Current version only takes text input Requires a server (XHTML files are delivered by a CGI script on a server) Database storage “Undo” option User-friendly methods for setting parameters
