Research methods Flashcards
What are laboratory experiments and who favours them
Test hypothesise in a controlled environment where the researcher changes the independent variable and measures the effect on the dependent variable - favoured by positivists
Advantages of lab experiments
- Highly reliable (TS) - can specify precisely what steps were followed
- Can easily identify cause and effect relationships
- Can isolate variables (PS)
Disadvantages of lab experiments
- Artificiality - carried out in artificial environment, may not reveal how people act in real world
- Hawthorne effect (TL) - people know they are being studied
- Unrepresentative (TL) - small scale nature
- Impossible to identify/control all the variables that might exert influence on certain social issues (PL)
What are field experiments
take place in the real social world - sociologist either creates a situation or adapts a real life situation to their research purpose. Involved dont usually know research is taking place
Advantages of field experiments
- Less artificiality
- High validity - people unaware so no hawthorne effect - act normally
Disadvantages of field experiments
- People experimented on without informed consent (EL)
- Less control over variables (PL)
- Limited application - can only be applied to a limited number of social situations - may not be reliable (TL)
Advantages of questionnaires
- Cheap and quick (PS)
- Quantifiable data
- Representative - reach many (TS)
- Reliable - questionnaire can be easily repeated (TS)
- Consent when they answer because under no obligation to do so (ES)
Disadvantages of questionnaires
- Low response rate - may hinder representativity (TL)
- Low validity - people may be more willing to lie (TL)
- Interviewer cant ask follow up questions if participants don’t understand questions or say something interesting (PL)
What are structured interviews and who favours them
Use a list of pre set questions and all interviewees asked in same way
Favoured by positivists
Advantages of structured interviews
- Training interviewers is easy and cheap (PS)
- Cheap and easy to administer (PS)
- Representative (TS)
- Results easily quantifiable because they use close ended questions with coded answers (PS)
- Reliable (TS)
Disadvantages of structured interviews
- Lack of validity - close ended and pre coded answers may not fit what the interviewee wants to say (TL)
- People may lie or exaggerate (TL)
What are unstructured interviews and who favours them
mainly ask open ended questions that produce qualitative data rich in meaning
favoured by interpretivists
Advantages of unstructured interviews
- Can build a rapport - makes interviewee more comfortable
- Flexible - interviewer not restricted to a fixed set of questions
- Valid - people can be more truthful because conversation is not constrained
Disadvantages of unstructured interviews
- Time consuming
- Expensive to train interviewers
- Unrepresentative - small research samples
- Not reliable - because questions are open - cant be easily repeated by another researcher
What are semi structured interviews
qualitative method - combines pre-determined set of open questions with opportunity for interviewer to explore particular themes
Advantages of semi structured interviews
- Lots of data and detail generated
- Fairly flexible and sensitive
- Easier to analyse than unstructured interviews
Disadvantages of semi structured interviews
- Cant guarantee honesty of participants
- Cause and effect cannot be inferred
- Flexibility of interview may lessen reliability
- Open ended questions difficult to analyse
- Difficult to compare answers
What are participant observations
when the researcher joins in the activities of the group they are researching
Advantages of participant observations
- Valid - groups are observed in a natural and authentic setting so data more likely to be true
- Data is richly detailed and offers insight into social behaviour
Disadvantages of participant observations
- Unreliable - cannot be easily replicated because in natural environment
- Unrepresentative - small scale groups - not representative of wider population
- Researcher bias - might go native
- Difficult to ensure anonymity of participants (EL)
- Problems getting in and staying in group (PL)
What are non participant observations
Observer avoids any direct involvement with the research group
Advantages of non participant observations
- Valid - limited risk of the researcher “going native”
