Stages involved in designing + conducting research:
1) choosing a topic
2) Formulating an aim/hypothesis
3) Operationalising concepts
4) The pilot study
5) Sampling
- Research Design: choosing a topic
Sociologists need to decide what topic they wish to study. (this will be guided by your identity/passions, world issues, reasons for patterns/trends in society)
- Research Design: Formulating aim or hypothesis
This aim/hypothesis will be tested. aim identifies what sociologist intends to study, hopes to achieve by conducting research.
Hypothesis could be an idea; predicted statement that can be tested. It gives direction to research + focus on questions to be asked. Requires sociologist to think up possible explanation. If evidence gathered shows hypothesis is false then must be discarded, and attention will be directed to new areas of research.
- Research Design: operationalizing concepts
To test: abstract ideas ,central to the hypothesis, must be operationalized. (measuring a variable, defining variable so it can be measured - necessary before research starts).
After ‘operational’ definition of concept - can write questions that measure it.
- Research Design: The Pilot Study
Next, need to produce pilot study : small scale study conducted before real study. Errors can be spotted + improved. Questionnaire or interview schedule can be finalized.
- Research Design: Sampling
Once topic of research decided, need to decide who should be included in their research - target/ research Population. Practical reasons- research cannot involve entire population - sociologists choose sample.
Purpose of sampling - ensure those selected are representative of larger target pop.
Results in generalizations that apply to all cases/ people of topic/ not just who they are studying - an example of macro sociology.
- Research Design: Sampling techniques
Use techniques/ methods to select sample for research.
- Representative sampling (RS):
Random - sample selected by chance eg. names drawn out of a hat. If large enough reflect characteristics (gender/ethnicity/class) of whole research pop. sometimes not large enough to ensure representativeness.
Quasi - Random/systematic - (high level random sampling) every nth person in sampling frame (SF) is selected.
Stratified random - firstly breaks down pop of SF by age/gender/ethnicity. sample created in same proportions eg. if 20% of pop U18, 20% sample U18.
Quota - pop is stratified. each given quota of say 20 females + 20 males- they have to fill w/ respondents who fit criteria .Interview does this till quota is filled.
- Non-representative sampling: Interpretivists engage in micro level analysis. more concerned w/ valid understanding of behavior. Reasons why cant create RS: social characteristics of pop may not be disclosed; impossible to find or create sampling frame for particular research pop, respondents may refuse to participate. what sampling they do instead:
Snow-ball - collect sample by contacting no of individuals, ask them to suggest others who would participate, thus adding to sample. creating a network. NOT RS.
opportunity - choosing from individuals who are easiest to access or a captive audience. NOT RS.
Name all representative and Non-representative sampling techniques:
RS: Random Quasi- Random/ systematic Stratified Random Quota Non RS: snowball opportunity
Advantages of a Lab Experiment
- Can establish cause and effect relationship between independent + dependent variables - allows scientists to predict accurately what will happen in the future.
- can replicate lab experiments - if follow exact same steps. method is therefore reliable.
- detached method - scientists’ personal feelings/ opinions have no effect on outcome of experiment.
- Positivists favor this method as see it as an objective way to conduct research modelled on scientific methodology.
Disadvantages of a Lab Experiment
- society is very complex - impossible to identify/control all variables that might impact on behavior.
- small-scale nature of the experiment reduces representativeness
- artificial environment where the experiment takes place (lab) means unlikely behavior is true or valid.
- Hawthorne Effect - if people know they are being studied, the knowledge will impact on their behavior by changing it - again reduces validity.
Field experiments as a better alternative to Lab experiments:
- take place in subjects natural surroundings rather than artificial environment - more valid + realistic.
- To avoid Hawthorne Effect, participants aren’t aware they are taking part in experiment (critics argue unethical).
- Because they’re more realistic - less scope for control over variables.
comparative method
carried only in mind of sociologist. ‘thought experiment’. researcher doesn’t experiment on real people at all. Still designed for identifying cause + effect relationships. How it works:
1) identifies 2 groups of people that are alike in all major aspects except for one variable they’re interested in.
2) then compare 2 groups to see if one difference between them has any effect.
