What this dot point is asking
OCR Component 2 expects you to evaluate secondary data, sources collected by others: official statistics and documents, plus content analysis. You need the hard/soft statistics distinction, the types of document, and the debate between positivists, who treat statistics as social facts, and interpretivists, who argue statistics are socially constructed. All applied to inequality.
The answer
Official statistics
Positivists value official statistics as cheap, large-scale, representative social facts that reveal patterns and trends over time, ideal for studying inequality in income, employment or health. Interpretivists counter that statistics are socially constructed: they reflect official definitions, recording practices and patterns of non-reporting, so for example racist incidents or domestic abuse may be heavily understated. A statistic, on this view, tells you as much about how it was collected as about the world.
Documents
Documents are written or recorded sources:
- Personal documents (diaries, letters, photographs, social media posts) offer rich, valid insight into meanings.
- Public documents (government reports, media, school and court records) are widely available.
- Historical documents (archives, old newspapers) allow the study of the past.
Documents are strong on validity but their authenticity (is it genuine?), credibility (is it sincere and accurate?) and representativeness can be uncertain.
Content analysis
Content analysis systematically studies the content of documents and media. It can be quantitative (coding and counting themes, such as how often a group appears) or qualitative (interpreting meaning). It is widely used for analysing media representations of class, gender and ethnicity. The choice of secondary source, like any method, is shaped by practical, ethical and theoretical (PET) factors.
Examples in context
A top answer weighs the positivist trust in statistics against the interpretivist critique that they are socially constructed, and applies both to the named inequality.

Q1. Outline two types of document used in sociological research. [4 marks]
- What the marker wants. Two types (AO1, two marks each): personal documents such as diaries, and public documents such as government reports, each briefly explained.
Q2. Outline and explain two reasons why interpretivists are critical of official statistics. [10 marks]
- Cue. Two developed points: statistics are socially constructed by definitions and recording practices, and non-reporting means soft statistics understate hidden problems, each applied to an example such as crime or domestic abuse.

OCR H580/02 201810 marksOutline and explain two advantages of using official statistics to study social inequality. [10]Show worked answer →
An Outline and explain question (AO1 and AO2). Each advantage needs explanation and an applied example.
Advantage one. Scale and cost: official statistics cover huge populations and are already collected, so they are cheap and quick and allow patterns and trends to be tracked, for example government income data revealing the wealth gap.
Advantage two. Representativeness and comparison: large-scale official data is broadly representative and lets researchers compare groups and years, for example comparing employment rates by ethnicity over time. The top band applies each advantage to inequality.

A research-methods evaluation question (AO1, AO2 and AO3) marked by levels of response. Apply PET to the context.
Strengths. Positivists value official statistics on ethnicity as cheap, large-scale, representative social facts that reveal patterns (employment, income, stop and search) and trends over time.
Limitations. Interpretivists argue statistics are socially constructed: definitions of ethnicity, recording practices and non-reporting shape the figures, so "soft" statistics such as racist incidents may understate the problem.
Judgement. Official statistics are valuable for mapping the scale of ethnic inequality but must be read critically, as they reflect how they were collected. Applying PET to the context reaches the top band.
