Theory & Methods Flashcards
laboratory experiments
- favored by positivists, lab experiments test hypotheses in a controlled environment where the researcher changes the independent variable and measures the effect on the dependent variable.
advantages of lab experiments
- highly reliable
can be replicated and the original experiment can specify what steps were followed in the original experiment. - can easily identify cause and effect relationships.
disadvantages of laboratory experimens
- artificiality
lab experiments are carried out in a highly artificial environment and may not reveal how people act in the real world. - the Hawthorne effect
a lab is not a formal or natural environment if people know they are being studied they may act differently. - the researcher needs informed consent of the participant
E.G. SPE (participants were not fully informed of the experiment) - the research may show elements of deception in order to find out the cause effects
Questionnaire
- favored by positivists, written or self-completed questionnaires are a form of social survey and can be distributed in a range of ways - notably, via post, emailed, or handed out in person.
- questionnaires are typically a list of pre-set questions that are close-end questions with pre-coded answers.
advantages of questionnaires
practical - questionnaires are cheap and quick
representative - can reach a geographically widespread research sample
reliable - can be easily replicated due to how the questions are pre-set
limited ethical issues - the respondent is under no obligation to answer the question
disadvantages of questionnaires
response rate - postal questionnaires in particular obtain a low response rate, which may hinder the representativity
low validity - people may be more willing to lie
unrepresentative - you are likely to get a certain group of people who would be more willing to answer the questionnaire.
structures questionnaires arent qualitative
structured interviews
- involve face-to-face or over-the-phone delivery of questionnaire
- use a list of pre-set questions designed by the researcher and asked of all interviewees in the same way
advantages of structured interviews
practical - training interviews and administrations is easy and cheap
representative - can reach a geographically wide research sample
results are easily quantifiable because they use close-ended questions with coded answers.
reliable -
researchers don’t require a set amount of interpersonal skills
disadvantages of structured interviews
lack validity - people may lie f exaggerate
may be time consuming to organize
official statistics
- quantitive data collected by government bodies
- data is quick cheap and easy to access and is easy to access and covers a wide range of social issues
advantages of official statistics
practical - cheap and easy to obtain
easy to access
can easily identify and cross-examine cause-and-effect relationships
representative - often large groups of people
reliable - have to be filled out by law
disadvantages of official statistics
- the government collects these for its own benefit, misinterpreted by sociologists.
- could have a hidden agenda or miss key info
- definitions may be different
unreliable - census coders may make errors or people may fill them out incorrectly
- doesn’t reveal the reasons why the statistics are the way they are.
unstructured interviews
the interpretivists - favored method of unstructured interviews
- mainly ask open-ended questions that produce qualitative data, rich in meaning
- there is a strong relationship built between the interviewer and interviewee = means the data is more likely to be valid
advantages of unstructured interviews
rapport - the informality allows the interviewer to develop a relationship with the interviewee
flexibility - the interviewer is not restricted to a fixed set of questions
valid - they are flexible due to how the conversation is not constrained by fixed questions, people can therefore be more truthful.
disadvantages of unstructured interviews
impractical - due to how unstructured interviews are typically longer, they consume ire time and have a smaller research sample
impractical - interviewers need specific interpersonal skills which may be more costly and time-consuming to get
unrepresentative - due to how there is a small research sample, the data obtained is not representative of the wider population
unreliable - due to how the questions are open they cannot easily be repeated by another researcher.
additionally the respondents ability to respond in a way they wish makes it impossible to clarify their responses
