Dados de um questionário a 50 professores londrinos.
A study of values and attitudes among fifth formers in a North London comprehensive school.
This survey of teenage attitudes and opinions in a North London comprehensive school (11-18 mixed) was designed and conducted, under my guidance and supervision, by three of my sophomore students as part of their group research dissertation for BA Applied Social Studies (Social Research) at the Polytechnic of North London (PNL, now part of London Metropolitan University). . It aimed to discover something about pupils’ future expectations and awareness of, and attitudes towards, various current social issues and problems, particularly racism and sexism. It replicates various items and scales from other work (Wilson-Patterson, Eysenck, Himmelweit, Srole-Christie) particularly the St Paul’s Girls senior pupils study (Feb 1973) some of which were also used in the SSRC Survey Unit Quality of Life surveys 1971-75.
The self-completion questionnaire was completed in December 1981 by all fifth form pupils present on the day of the survey (N=142). It was administered during time-tabled Social Studies classes and, time permitting, was followed by discussion with class teachers and the PNL students of the issues covered in the survey.
Given the particularly high quality of this project, a user manual was prepared by John Hall and Alison Walker for use with the postgraduate Survey Analysis Workshop and the undergraduate course Data Management and Analysis. It serves as model documentation for similar small survey projects.

Alguma informação sobre a qualidade de vida na inglaterra
I have recently been making extensive revisions in the area of Subjective Social Indicators and it now makes more sense to split the page into three sections. Previous contents of his page have now been spread across several new pages.
Quality of Life: Measurement and methodology
There has been intense (often polemical) debate over the years on methodology and measurement of the concept “Quality of Life” and there is a variety of working definitions deriving from diverse academic disciplines and political perspectives. This page lists sources of philosophical and disciplinary arguments for and against quantitative research on subjective social indicators.
Measures of psychological well-being
This page will list scales to measure psychological well-being, tried and tested in the field on general populations. Scales tested on students will not be listed, unless they have also been used on general populations. See also:
SSRC Survey Unit Quality of Life in Britain surveys 1971 – 1975
Summary information and detailed abstracts on all “Quality of Life in Britain” surveys conducted at the SSRC Survey Unit between 1971 and 1975 by Mark Abrams and John Hall. (Variables, fieldwork, sampling, facsimile questionnaires, user-manuals, data sets, publications.)

Alguns recursos sobre estudos por inquérito.
This section covers survey methods in general and has links to useful resources, but there are no learning materials as such.
For a good general introduction, see What is a survey? (American Statistical Association booklet, 68 pp., 2004 by Fritz Scheuren: combines as chapters a series of separate earlier pamphlets starting with What is a survey? by Robert Ferber, Chair, Paul Sheatsley, Anthony Turner and Joseph Waksberg, ASA, 1980 )
Flow diagram of the stages of a survey (from page 8 of Scheuren above). These days we should perhaps add a Stage 7: Secondary analysis

What is SPSS and what does it do?
SPSS consists of an integrated series of computer programs which enable the user to read data from questionnaire surveys and other sources (e.g. medical and administrative records) to manipulate them in various ways and to produce a wide range of statistical analyses and reports, together with documentation.
Most users will have access to SPSS via their college or workplace or by purchasing the Gradpack version (specially priced for students). Full details are on IBM SPSS Solutions for Education and there is a comparison table showing what is available in each version.

Welcome to the
IFCS Cluster Benchmark Data Repository
The aim of this Repository is to stimulate better practice in benchmarking (performance comparison of methods) for cluster analysis by providing a variety of well documented high quality datasets and simulation routines for use in practical benchmarking.
The repository collects datasets with and without given “true” clusterings. A particular feature of the repository is that every dataset comes with a comprehensive documentation, including information on the specific nature of the clustering problem in this dataset and the characteristics that useful clusters should fulfill, with scientific justification.
- Read more about the philosophy of the repository.
- Go directly to the list of available data sets.
Note: Up to May 15, 2017 a data set may be analyzed within the framework of a challenge! More information on this challenge is available here.
