What this dot point is asking
The SQA wants you to explain how sociologists judge research, through reliability, validity and representativeness, and the ethical rules they must follow. Because Higher Sociology asks you to evaluate research methods, these criteria are the tools you use to judge any study, and ethics often explain why some methods cannot be used.
The answer
Reliability
Validity
Representativeness
Research ethics
Why ethics can limit methods
Ethics are not just a checklist; they shape what research is possible. Covert observation breaks informed consent and uses deception, so it is hard to justify even though it avoids the observer effect. Studying vulnerable groups or sensitive topics raises the risk of harm, so researchers must weigh the value of the knowledge against the cost to participants.
Examples in context
The trade-off between reliability and validity shows clearly when comparing methods. A structured questionnaire on attitudes to crime is reliable, anyone could repeat it and get comparable results, but its closed questions may produce shallow or untruthful answers, lowering validity. An unstructured interview on the same topic is more valid, because the researcher can probe and the respondent explains in depth, but it is hard to repeat exactly, so it is less reliable. Ethically, both must protect participants through informed consent, confidentiality and the right to withdraw, which is why a covert study, however valid, is so hard to defend. Weighing reliability, validity, representativeness and ethics together is exactly the kind of judgement that earns top marks in an evaluation answer.

Q1. Explain what is meant by validity in sociological research. [4 marks]
- Cue. Research is valid if it really measures what it claims to and gives a true picture of social reality.
Q2. Describe two ethical principles a sociologist should follow. [4 marks]
- Cue. Informed consent (participants agree, knowing what is involved) and confidentiality (data kept private and anonymous so people cannot be identified).

An -mark "explain" question. Markers want a clear contrast developed with examples.
Reliability is about consistency: research is reliable if repeating it would produce the same results, so it can be checked. Validity is about truth: research is valid if it really measures what it claims to and gives a true picture of social reality.
Develop the contrast with method examples: structured questionnaires are reliable (easy to repeat) but can lack validity (shallow, untruthful answers), while unstructured interviews and observation are often more valid (deep, true) but less reliable (hard to repeat). Showing that the two can pull in opposite directions earns the developed marks.
SQA Higher 20198 marksExplain why ethics are important in sociological research.Show worked answer →
An -mark "explain" question. Markers want the main ethical principles explained and linked to practice.
Ethics protect the people being studied. Researchers should gain informed consent (participants agree, knowing what is involved), keep data confidential and anonymous, avoid harm to participants, and be honest, avoiding deception.
Develop it by linking ethics to method choice, for example that covert observation breaks consent and uses deception, so it is hard to justify ethically. An example, such as anonymising data so participants cannot be identified, earns the developed marks.
