| WebQ - WebQ is a JavaScript application for Q-sorting questionnaire items online. Q-sorting can be characterized as a process whereby a subject models his or her point of view by rank-ordering items into 'piles' along a continuum defined by a certain instruction (McKeown & Thomas, 1988, p. 30). Demo Available. | |
| WinIDAMS
1.0 for 32-bit Windows Operating System. Released
by UNESCO - WinIDAMS is a freeware software package for numerical information
processing and statistical analysis. It provides a complete set of data
manipulation and validation facilities and a wide range of classical
and advanced statistical techniques, including interactive construction of multidimensional tables, graphical exploration of data and time series analysis. Freeware |
