CREATE & MANAGE DATA
DOCUMENTING YOUR DATA
Study-level documentation provides an overview of: the research context and design, data collection methods, data preparation and results or findings. It is key to enabling the secondary user to make informed use of the data.
Good study-level data documentation includes information on:
- the context of data collection: project history, aims, objectives and hypotheses
- data collection methods: data collection protocols, sampling design, instruments used, hardware and software used, data scale and resolution, temporal coverage and geographic coverage, and digitisation or transcription methods
- structure of data files, number of cases, records, variables and relationships between files
- data sources used and provenance of materials, e.g. for transcribed or derived data
- data validation, checking, proofing, cleaning and other quality assurance procedures carried out, such as checking for equipment and transcription errors, calibration procedures, data capture resolution and repetitions, or editing, proofing or quality control of materials
- modifications made to data over time since their original creation and identification of different versions of datasets
- for time series or longitudinal surveys, changes made to methodology, variable content, question text, variable labelling, measurements or sampling
- information on data confidentiality, access and use conditions, where applicable
Data documentation can be provided by data depositors in the form of final reports (e.g. ESRC End of Award Report), technical reports, working papers, laboratory books or publications. Important data documentation would be questionnaire copies, interviewer instructions, interview topic guides or experimental protocols.
