A tale of UCAS and SPSS: taking today’s data from an
intricate database and producing comprehensible management-
friendly comparative statistics by 10 a.m.
Charles LeeSheila Buckthorpe
Mathematics, University of Bolton
Abstract
UCAS data is fed to and from universities as a series of transactions for each student, with a typical student having 15 to 20 transactions over the year. At any date in the applications cycle it is useful to be able to show how this year’s applications compare to last year’s, for both a whole university and for individual courses. SPSS is an ideal tool for this. Particularly valuable are its good data capture facilities, the ability to program in syntax files, and the ease with which comprehensible graphs and tables can be constructed. In addition, the ability to build a syntax file to perform the entire task makes it feasible to produce complex reports from data which is only an hour or two old.
Included in this talk will be some of the data manipulation features of SPSS which enable strange and wonderful things to be done with very messy data.
