This comprehensive Cambridge International IGCSE Sociology 0495 Research Methods PowerPoint introduces Year 10 students to the different types of data and evidence used by sociologists. It is closely structured around Topic 1 Research Methods, with particular emphasis on 1.2 Types of Data and Evidence and Paper 1 source-based skills.
Students learn the important distinction between data and evidence, before exploring primary and secondary data and qualitative and quantitative data. The lesson shows how these categories can overlap, for example primary qualitative evidence from interviews or secondary quantitative evidence from official statistics.
The resource also examines key forms of secondary evidence, including official statistics, historical and personal documents, digital sources and media content. Students are encouraged to consider who produced the evidence, why it was produced and whether it may contain gaps or bias.
The lesson develops students’ understanding of the strengths and limitations of different forms of evidence, with clear coverage of validity, reliability, representativeness, generalisability, bias and ethics. It also links evidence to different research methods, including questionnaires, structured and unstructured interviews, observations and documents/media.
A theory section reinforces the relationship between positivism and quantitative evidence and interpretivism and qualitative evidence, while also introducing mixed methods and triangulation.
