Component 2: observation (participant and non-participant, overt and covert) and experiments (laboratory, field, comparative and natural), their practical, ethical and theoretical strengths and limitations, and concepts including the Hawthorne effect and going native.

What this dot point is asking

OCR Component 2 expects you to evaluate observation and experiments: their types, their practical, ethical and theoretical (PET) strengths and limitations, and key concepts such as the Hawthorne effect and going native. Observation is favoured by interpretivists for its validity; experiments by positivists for control and reliability. Both must be applied to the study of inequality.

The answer

Observation

Participant observation is favoured by interpretivists because it produces high validity: living among a group gives a rich, first-hand understanding of their meanings in a natural setting, uncovering things a survey would miss. Its weaknesses are that it is hard to repeat (low reliability), small-scale (low representativeness), and threatened by the Hawthorne effect (people change behaviour when they know they are watched) and going native (the researcher over-identifies with the group and loses objectivity). Covert observation adds ethical problems: deception and the absence of informed consent.

Experiments

Experiments seek cause and effect by controlling variables:

• Laboratory experiments offer high control and reliability but are artificial (low validity for real-life behaviour) and raise ethical issues about manipulating people.
• Field experiments take place in real settings, so they are more natural, but allow less control over variables.
• The comparative method (used by Durkheim) compares groups or societies using existing data, and the natural experiment studies a naturally occurring change the researcher did not create.

Positivists favour experiments for their control and reliability; interpretivists criticise their artificiality, arguing they cannot capture meanings. As always, choice is shaped by practical, ethical and theoretical (PET) factors.

Examples in context

A top answer applies each point to the named group and uses PET, rather than listing generic strengths and weaknesses of observation.

• What the marker wants. Two types (AO1, two marks each): participant versus non-participant, or overt versus covert, each briefly defined.

Q2. Outline and explain two reasons why interpretivists favour participant observation. [10 marks]

• Cue. Two developed points: it produces valid, first-hand data on meanings in a natural setting, and it lets the researcher understand the group from the inside (Verstehen), each applied to a study of an inequality.
