Benefits of the large-scale government datasets
• good quality data– produced by experienced research organisations– UK/GB - usually nationally representative with large samples. Interviewers
all over country– good response rates– well documented, NISRA, ONS, UKDA, QB etc.
• continuous data– e.g. Continuous Household Survey 1983, allows comparison over time– data is largely cross-sectional
• hierarchical data– individual and household– intra-household differences– household effects on individuals
![Page 13: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/13.jpg)

• allow researchers to analyse change at the individual level
• more complex to analyse
![Page 15: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/15.jpg)
British Household Panel Survey • collected and deposited by the ULSC at Essex
• follows the members of 5500 households first sampled in 1991
• interviews conducted annually
• become a major resource for understanding the dynamics of British households
• coverage includes:– income, labour market behaviour, social and political values,
health, education, housing and household organisation
• recently large new samples were introduced in Scotland, Wales and Northern Ireland.

![Page 27: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/27.jpg)
Using ESDS data for teaching
• tutor registers with ESDS and downloads data
• registers a usage (for micro data)
• tutor makes data available to students (if online only via secure network)
• tutor asks students to register or sign access agreement for teaching (not always necessary, but to be encouraged)
![Page 28: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/28.jpg)
Data repurposed for teaching - examples
• teaching datasets (available for download and via Nesstar) based on ELSA, NCDS, BHPS, HSE, BCS, LFS, GHS)
• X4L Survey Data in Teaching• CHCC Learning and Teaching Materials
Registration not required -
• Practical Exemplars on the Analysis of Surveys• Understanding Social Statistics• Teaching Resources and Materials for Social Scientists
(TRAMSS)
![Page 29: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/29.jpg)
Repurposing data – issues to consider
• UKDA is guardian for the data/does not own the data• data can usually only be accessed by registered users • most data can be incorporated into teaching packages/courses but
access restricted to the relevant students and not made publicly available e.g. on the web (some exceptions)
• any derived data must be offered for deposit with UKDA• permission of data owners – where data are repurposed and to be
made publicly available, permission of data owners must be sought
• copyright e.g. LFS teaching dataset Crown copyright held jointly with the ESDS
• IPR of authors of repurposed material• information on how to cite and acknowledge data
![Page 30: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/30.jpg)
X4L Survey Data in Teaching: a resource for students and
teachers
Aimed to increase the use of real data in the classroom. A grander mission is to improve the data literacy of A level and university students to:
enable a better understanding of the use of social science data as applied to real-life problems
enhance skills in manipulating numerical data in textbooks, newspapers or reports
become critical consumers of this data
![Page 31: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/31.jpg)
Project rationale• UKDA datasets are used extensively in academic
research
• but underused in T&L programmes within HE, and in further education
• UKDA has the potential to offer its resources to the T&L communities for developing more ‘packaged’ resources BUT needs the advice and input from instructors in the classroom on how to re-purpose and apply the content
• UK skills shortage of quantitative analysts is now critical - introducing concepts early on in post-16 education is one way to redress this shortage
![Page 32: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/32.jpg)
Topics and educational level• X4L SDiT uses the study of crime in society to
show how existing data sources can be utilised• relevant to a range of social science disciplines,
such as sociology, politics, psychology, media studies and citizenship studies.
• research methods in social science— potential of survey data to answer questions— survey measurement; sampling— basic data management/basic data analysis— resource discovery skills
• applicable to ‘A’ level syllabi but also for undergraduate and postgraduate learning
![Page 33: The Economic and Social Data Service (ESDS) Karen Dennison Economic and Social Data Service UK Data Archive Swansea College 27 January 2006](https://reader035.vdocuments.us/reader035/viewer/2022081519/56649f2a5503460f94c43bb7/html5/thumbnails/33.jpg)
Overview of the learning and teaching materials
• modules on the use of crime data (four modules) using Nesstar online data exploration system resource discovery at the UK Data Archive
• a teaching version of the British Crime Survey dataset available from the UKDA/via Nesstar
• appendix on sampling and statistical inference• glossary of statistical terms• free demonstration version of very simple and user-
friendly data analysis software, which is utilised in the last two of the teaching modules
