How much of WJEC GCSE Sociology is research methods?

In each examination series, at least 15 percent of the available marks are awarded for knowledge and understanding of research methods. Research methods are also expected to permeate the whole course, so they can appear in questions on families, education and other topics, not only on their own.

What is the difference between primary and secondary data?

Primary data is information the researcher collects themselves, first-hand, for example through a questionnaire, interview or observation. Secondary data already exists and was collected by someone else, such as official statistics, newspaper reports or previous studies.

What is a representative sample?

A sample is the smaller group studied to stand for a larger population, drawn from a sampling frame. A representative sample reflects the wider group in things such as age, gender and class, so the findings can be generalised. Methods include random and quota sampling.

What is the difference between reliability and validity?

Reliability means the research could be repeated and would give similar results, so it is consistent. Validity means the research measures what it claims to measure, giving a true picture. Research can be reliable without being valid, or valid without being reliable.

Sociological research methods: a complete overview for WJEC GCSE Sociology (Component 2)

Q: What are the main primary research methods?

The main primary methods are questionnaires (written questions for many people), interviews (structured or unstructured), observations (participant or non-participant, overt or covert) and experiments. Each has strengths and weaknesses and produces a particular kind of data.

A complete overview of sociological research methods in WJEC GCSE Sociology Component 2, covering the research process and types of data, the primary methods, sampling and secondary sources, and the practical, ethical and theoretical considerations that shape research.

What this covers

Sociological research methods is examined as part of Component 2 of WJEC GCSE Sociology, and at least 15 percent of the marks in each series go to research methods. The board also expects research methods to permeate the whole course, so the ideas here can appear in questions on families, education and other topics. This overview ties the dot points together: the research process and types of data, the primary methods, sampling and secondary sources, and the considerations that shape research.

The research process and types of data

Research moves through stages: an aim, often a hypothesis, a pilot study, a method, a sample, data collection, analysis and conclusions. Data is primary (first-hand) or secondary (already exists), and quantitative (numbers) or qualitative (words and meanings).

Methods, sampling and sources

The main primary methods are questionnaires, interviews (structured or unstructured), observations (participant or non-participant) and experiments, each with strengths and weaknesses. A sample is drawn from a sampling frame and should be representative, using methods such as random or quota sampling. Secondary sources include official statistics and the mass media.

Considerations

Choosing a method depends on practical factors (time, money, access), ethical factors (consent, confidentiality, avoiding harm) and theoretical factors (the kind of data wanted). Research is judged by its reliability (consistency) and validity (truth).

Research is judged by its reliability, meaning it could be repeated with similar results, and its validity, meaning it measures what it claims to measure.

Solutions

Q1: Primary data is collected first-hand by the researcher (questionnaire, interview); secondary data already exists and was collected by someone else (official statistics, newspapers).
Q2: Quantitative data is in the form of numbers (a percentage); qualitative data is in the form of words and meanings (how people feel).
Q3: Strength: questionnaires reach many people quickly and cheaply with comparable data. Weakness: people may not answer honestly, and there is no follow-up, so the data can lack depth.
Q4: Participant observation: the researcher joins in, giving deep insight but possibly changing behaviour. Non-participant observation: the researcher watches without joining in, more detached but with less insight.
Q5: A sample is the smaller group studied to stand for the population; it should be representative so the findings can be generalised.
Q6: Any two, described: official statistics (government figures, good for patterns) and the mass media (newspapers, television, showing how issues are presented but possibly biased).
Q7: Any two of: informed consent, confidentiality and protecting identities, avoiding harm, and honesty (avoiding deception).
Q8: Reliability means the research could be repeated with similar results (consistent); validity means it measures what it claims to measure (true).
