Research Methods Flashcards
Process of research (6 steps)
- Aim and hypothesis
- Operationalise variables
- Choose research method
- Carry out a pilot study
- Choose sampling method
- Collect data
Practical issues ( explaination & name 3)
Things preventing you from actually carrying out the research or reaching participants
Time, money, funding body, personal skills and characteristics, subject matter and reaserch opportunity
Ethical issue (explain & name them)
Moral issues of right and wrong when dealing with participants
Protection from harm
Confidentiality
Deception
Right to withdraw
Informed consent
Privacy
Theoretical issues (explain & name 4)
Whether accurate and truthful results are obtainable
Validity, reliability, representativeness, methodological perspective
Random sampling
Every member of target population gets an equal chance of being chosen (eg names in a hat)
Stratified sampling
Target population is divided into subgroups/ stratas based on characteristics and the participants are chosen randomly in proportion to subgroups
Systematic sampling
Every nth person of the sampling frame is selected
Quota sampling
The researcher identifies characteristics of target population and people who fit the criteria volunteer
Opportunity sampling
Participants who are accessible at the time and are willing to take part in
Snowball
Researcher finds small group who is representative of the target population and they ask others to participate
Random sampling advantages
Non bias as everyone has an equal chance
Random sampling disadvantages
Might not be representative as people with similar characteristics can be chosen by chance
Need to have access to list of whole target population
Stratified sampling advantages
Unbias target population have equal chance of selection
Most representative as sample is proportional to the whole of the target population
Stratified sampling disadvantages
Can be very time consuming to identify all subgroups then choose randomly from each
Can be difficult to choose a single charecteristics to divide target population into
Systematic sampling advantages
Non bias as long as nth number is chosen at random
Systematic sampling disadvantages
Might not be very representative
Can be time consuming
Quota sampling advantages
Non bias as researcher doesn’t choose participants
Easy
Quota sampling disadvantages
Not representative as the same kind of people are likely to volunteer
Opportunity sampling advantages
Quick and easy
Opportunity sampling disadvantages
Unrepresentative
Snowball sampling advantages
Useful for finding participants who may be hard to reach or unlikely to participate in reasearch
Find target population easily ounce you find the initial person
Snowball sampling disadvantages
Can be unrepresentative
Time consuming
Aim of pilot study
To fix any problems, give interviewers / observers practise, clarify and refine questions
questionnaires DISADVANTAGES
P - low response rate > unrepresentative
P - inflexibility (one questionnaires are finalised researchers can’t explore new areas of interest or ask follow up questions)
T - respondents can easily lie or forget information > validity
T - questions may impose researchers own opinions (close questions can be leading)
T - data tends to be limited, unable to obtain full picture of experiences and feelings
T - don’t capture how people’s attitudes and behaviours change
questionnaires ADVANTAGES
P - time and cost efficient
E - less ethical issues than most research methods
T - positivists favour bc researcher remains detached > unbiased and objective
T - reliability > can easily be replicated and produce similar results
Interviewer bias
When the interviewer’s own personal opinions influence the respondents answers
Focus group
An interview around a specific topic where participants are encouraged to discuss personal feeling opinions and experiences. The interviewer’s role is to give questions or topic ideas and keep participants on topic
Semi structured interviews
Interviewers have a set list of questions but are allowed to ask additional follow up questions
Mix of open and closed questions
Unstructured interviews
The interviewer had a list of prompts and topics to discuss but interviewers have freedom to vary questions and wording
Open ended questions
