Topic 1: Quantitative research methods Flashcards
positivism
- model research methods on natural science
- Produce Objective, true, scientific knowledge
- cause and effect
interpretivism
- prefer quantitative data
- Gives us a ‘feel’ for what something is like
- deeper meaning
Key features of lab experiments
Control: controlled experiment. Artificial environment test hypotheses. Split into experimental (IV) and control group
cause and effect: condition of both groups measures before and after. Discover cause and effect relationship predict future outcomes (say in exam)
practical issues: open systems
keat and Urry - lab experiments are only suitable for studying closed systems where the researcher can control all the variables. Society is an open system with countless variables. Unsuitable for studying social phenomena
practical issues: complexity
no humans are alike, impossible to match experimental groups
practical issues: past
cannot be used to study people in the past, cannot keep people in lab experiments for a long time
practical issues: samples
only study small samples eg impossible to study members of a major religion. Small samples risk the appearance of variables just being a chance correlation
practical issues : expectancy effect
experimenter bias, what a researcher expects to happen can affect the outcome
ethical issues: informed consent
participants should be informed by the nature of the experiments, however, this is self defeating as they may act differently
ethical issues: Harm
some argue that minor harm can justified to yield social benefits. Experiment group may be benefitting from treatment, should be given to control group link to milgram
theoretical issues positives
+ replicability: experimenter can control the conditions, produces quantitative data so can be rerun and it is a very detached method
+ predictions: effective way to test hypotheses and make predictions
theoretical issues negatives
representativeness: lack external validity due to only studying small samples and artificial conditions
internal validity: Hawthorne effect may produce invalid results
free will: humans can make their own choices
Field experiment
Different to lab because it takes place in the subjects natural surroundings and those involved do not know they are the subject eg Rosenthal and Jacobson
positives of field experiment
+ artificiality: avoids artificial conditions of a lab, much more natural and valid for real life
state a type of field experiment
correspondence tests eg Brown and Gay studied racial discrimination in the workplace, sent applications to 1000 vacancies from 3 ethnicities
negatives pf field experiments
- variables: less control over variables, cannot be certain we have identified the cause
- unethical: subjects have no knowledge/ consent
what are close ended questionnaires
- force choice q’s
- limited possible answers
- recoded for analysis
what are open ended questionnaires
- free to answer how they choose to
- no preselected questions
