What this dot point is asking
The SQA wants you to explain and evaluate observation and experiments. Because Higher Sociology asks you to evaluate research methods, you must know the forms each takes (participant and non-participant; covert and overt; laboratory and field), the data they produce, and their strengths and weaknesses.
The answer
Participant and non-participant observation
Covert and overt observation
Laboratory and field experiments
Linking methods to validity and reliability
Observation is strong on validity (it captures real behaviour and meaning) but weak on reliability (it is hard to repeat). Experiments, especially laboratory ones, are strong on reliability but can be weak on validity. Recognising this trade-off is central to evaluating these methods.
Examples in context
A study of a youth subculture shows observation at work. By joining the group as a participant observer, a researcher can see how members really talk, dress and behave, capturing meanings and group rules that a questionnaire would miss, which gives high validity. If the work is covert, the group behaves naturally because it does not know it is being studied, but the researcher deceives the participants and gathers no consent, a serious ethical problem; if overt, the group may act differently because it is being watched. Because the study cannot easily be repeated and the findings come from one group, they are hard to generalise. Weighing this deep validity against the weak reliability, the difficulty of generalising, and the ethics of covert work is exactly the balanced judgement an evaluation question rewards.
Try this
Q1. Explain the difference between covert and overt observation. [4 marks]
- Cue. Covert means the group does not know it is being studied (more natural but unethical); overt means it does (more ethical but risks changed behaviour).
Q2. Describe one strength and one weakness of laboratory experiments in sociology. [4 marks]
- Cue. Strength: controlled and reliable, easy to repeat. Weakness: artificial setting reduces validity and may not reflect real life.

An -mark "evaluate" question. Markers want strengths and weaknesses weighed and a judgement reached.
Strengths: participant observation gives deep, valid, qualitative insight into how a group really behaves in its natural setting, capturing meaning that questionnaires miss, and it can reach groups that would not respond to surveys. Weaknesses: it is time-consuming, hard to repeat (low reliability), the observer may affect the group's behaviour, findings are hard to generalise, and covert observation raises serious ethical problems.
Evaluation marks come from judging when it is worth these costs, for example for studying a closed or deviant group where validity matters most. A clear judgement is the discriminator.
SQA Higher 20198 marksExplain the difference between laboratory and field experiments.Show worked answer →
An -mark "explain" question. Markers want a clear contrast developed with strengths and weaknesses.
A laboratory experiment is carried out in a controlled, artificial setting where variables can be tightly controlled, so it is reliable and easy to repeat, but the setting is unnatural and may not reflect real life. A field experiment takes place in a natural, real-world setting, so behaviour is more realistic and valid, but variables are harder to control and it is less easy to repeat.
Develop the contrast by noting that sociologists tend to favour field experiments because real-world validity matters, while laboratory experiments are rare in sociology. This earns the developed marks.
