A-Level Psychology: Research Methods — Hypotheses, Observation and Self-report

Research methods questions in A-level Psychology often hand you a short study and ask you to design part of it: write the hypothesis, choose behavioural categories, improve a questionnaire item or say what a control group would add. This material trains those design skills from the scientific processes section of current specifications (for example AQA's A-level Psychology for first teaching from September 2025, which added control groups to the list of controls and now refers to coding in content analysis).

The quiz begins with aims and hypotheses: telling an aim from a hypothesis, and choosing a directional hypothesis when previous research points one way. It then asks what a pilot study is for, why overlapping behavioural categories undermine an observation, and when event sampling is better than time sampling.

Self-report design is covered through closed and open questions and a flawed questionnaire item that is both double-barrelled and leading. You identify the features of a case study, and analyse a content analysis in which two researchers code magazine articles and compare their tallies to check inter-rater reliability.

The final questions deal with how research is reported and used: which section of a scientific report describes the participants and sampling method, why a study of a revision app needs a control group to provide a baseline, and how psychological research has implications for the economy, from therapies that shorten time off work to research that reduces wrongful convictions.

The material offers four formats. The 12-question quiz gives an explanation after every answer. The 18 flashcards cover the key terms, including structured and unstructured interviews and the sections of a report. The printable written work sets eight open design tasks with ruled space for handwritten answers that are then checked: writing hypotheses, designing behavioural categories with a sampling method, improving questionnaire items, designing an interview, planning a content analysis and explaining what belongs in an abstract. In the oral exam an examiner describes short studies one at a time, asks you to design or improve them and gives precise feedback at the end.

It complements the existing research-methods materials on design and analysis, which focus on experimental design, sampling of participants, reliability, validity and features of science, so together they cover the scientific processes more completely.

• Distinguish aims from hypotheses and write directional, non-directional and null hypotheses
• Explain the aims of pilot studies
• Design behavioural categories and choose between event and time sampling
• Construct questionnaire items and interviews, avoiding leading and double-barrelled questions
• Describe case studies and content analysis, including coding and inter-rater reliability
• Identify the sections of a scientific report, the role of control groups and the implications of research for the economy
