Sources of Data (AQA A-Level Sociology): Revision Notes
Documents
Documents serve as valuable sources of data for sociological researchers, offering access to information that might otherwise be difficult or impossible to obtain through primary research methods. Understanding how to effectively use and evaluate documents is essential for conducting thorough social research.
What are documents?
A document refers to any paper-based or electronic resource that contains recorded information. This broad definition encompasses various formats including written texts, audio recordings, video materials, and broadcast programmes. Documents can be contemporary or historical, providing researchers with windows into both present-day social phenomena and past events.
Researchers often begin their investigations with a literature search to establish the nature and scope of existing data. This preliminary step helps shape research directions and questions. In some cases, high-quality documents may make planned primary research unnecessary, as they already contain the required information.
Like all secondary data sources, documents must be used with caution due to potential errors, biases, and methodological limitations in their original compilation.
Types of documents
Personal documents
Personal documents include diaries, memoirs, letters, photographs, emails, and other personal electronic materials. These can be either historical or contemporary, created recently or long ago.
Personal documents are particularly valued because they represent a naturalistic arena where individuals freely explore their thoughts and feelings. Since most personal documents are not written for public consumption, they often possess high validity - they tend to be more honest and authentic than materials created for public audiences.
However, personal documents require careful evaluation. Diaries, for example, can be highly subjective since writers are selective about what they record and how they organise their thoughts. This selectivity can introduce bias and make it difficult to generalise findings from such individual sources.
Assessing personal document quality: Fulcher and Scott (2011) suggest four key questions for evaluating any historical document's reliability and validity:
- How authentic is the document? Is it complete and can it be credited to a particular author?
- What were the motives for writing the document? Is it creditable or exaggerated or biassed?
- Is the document representative or typical?
- Are the feelings and emotions expressed in the document clear?
Personal documents can provide more ecologically valid methods than traditional research approaches. They offer genuine insights into participants' thought processes that might not emerge through researcher-led interviews or observations, as people create them in their natural environments without artificial research constraints.
Some sociologists actively request participants to maintain diaries as part of their research design. Examples include Young and Willmott (1973) studying London families, Charles and Kerr (1988) examining families and food, and Jacqui Gabb (2008) who asked families to create emotion maps. Such researcher-requested diaries may have lower validity than naturally occurring ones. Alan Bryman (2012) notes that whilst email has largely replaced traditional letters, it can still provide an alternative document source for researchers.
Public documents
Public documents are materials produced for the public domain, created or received by government departments, executive agencies, armed forces, NHS authorities, and courts. These may overlap with official statistics and are typically stored in locations like The National Archives, with preservation rules governed by the Lord Chancellor.
Public records are generally not retained beyond 30 years unless specifically authorised. Researchers can access public records without obtaining consent, and confidentiality requirements do not apply to information within them.
Public documents typically provide accurate information and reflect factual aspects of society at specific points in time. They primarily offer quantitative data, though they may also contain qualitative insights about social conditions.
However, interpretivist and conflict sociologists question the usefulness of public documents, arguing that like official statistics, they primarily reveal information about the people or organisations that created them rather than providing objective social insights.
Advantages and disadvantages of using documents
Advantages
- Time-saving: Using existing secondary documents eliminates the need to collect data from scratch
- Rich qualitative insights: Personal documents like diaries provide genuine insights into behaviour and experiences
- Reliable alternative: Documents can substitute for traditional interview methods, especially for events that are difficult to recall or easily forgotten
- Supplementary method: Personal documents work well alongside questionnaires, interviews, or observations
- High validity: Personal documents often have high validity since they are typically not written for public reading
- Practical benefits: Useful when researchers cannot collect primary data due to financial constraints or distance issues
- Historical value: For certain establishments, policies, or groups, historical documents may be the only available information source
- Statistical potential: Sufficient public documents can enable creation of statistical databases
Disadvantages
- Representativeness issues: Documents often provide very personal accounts that may not be representative or generalisable
- Unknown honesty levels: No way to verify how honest individuals have been, affecting data validity and bias levels
- Definitional problems: People may operationalise concepts or define terms differently than researchers
- Unrepresentative samples: Research often focuses on unusual rather than ordinary people, leading to interesting but atypical examples
- Historical accuracy: Often impossible to check the accuracy of historical documents, especially when authors are deceased
- Interpretation difficulties: Ambiguities in historical documents can be difficult to resolve when authors are no longer contactable
Key research example
Research Example: Archer et al (2007)
Archer et al investigated how working-class ideas and identity influence young people's life choices, such as university attendance. They used photographic diaries completed by eight students, finding that young people subscribing to working-class youth styles were limiting their own access to academic success routes.
This study demonstrates how personal documents can reveal insights into social identity and decision-making processes that might not emerge through traditional interview methods.
Research application: Using diaries with learners
Krishan and Hoon (2002) studied course design in education, identifying three advantages of using diaries in research:
- They provide 'voices' to respondents, allowing them to write in their own words
- They offer insight into individuals' learning agendas
- They provide a means of 'listening' to respondents
The success of diary-based research depends entirely on the quality and frequency of entries. Short, infrequent entries compromise the method's usefulness.
Krishan and Hoon found that course design could be significantly improved if teachers understood learners' perceptions of desired content and learning methods. Often, teachers focus primarily on their own beliefs about course content and delivery methods. The disconnect between teachers' and learners' agendas can be problematic, making compatibility between these perspectives essential for meaningful learning and teaching.
By 'listening' to individual 'voices' through diaries, teachers can make classroom adjustments to accommodate individual learning needs more effectively.
Key Points to Remember:
- Documents are any paper-based or electronic resources that provide valuable secondary data for researchers
- Personal documents (diaries, letters, emails) offer high validity and naturalistic insights but may be biassed or unrepresentative
- Public documents provide accurate, mainly quantitative data but may only reflect their creators' perspectives
- Fulcher and Scott's four questions help evaluate document reliability: authenticity, motives, representativeness, and emotional clarity
- Documents can save time and provide rich data, but researchers must carefully consider issues of bias, representativeness, and historical accuracy
