methodology Flashcards
what are the 2 methodologies?
experimental and non experimental
observational research and what is it used for (applications)
studies behaviour in natural setting
what are 2 types of non experimental research?
observational and case study
pros and cons of observational research
pros;
natural setting
inexpensive
easy to conduct
observational research, how is it carried out (method)
an individual observe another individual or group in natural environment and records it
case study, what is it used for (application)
to gain detailed knowledge about an individual case
case study, how is it carried out (method)
no hypothesis to guide research
can study unusual conditions
method of snowballing sampling
participants X knows another participant with X, they recruit them
pros and cons of case study
pros;
Rich details about specific study
cons;
difficulty in applying to find wider population.
4 types of sample (selection of participants)
convenience sampling
snowballing
random
stratified
application of snowballing
researcher depends on small no. of participants to help them reach other subjects
like a chain
application of random sampling
each member of the population has an equal chance of being selected
pros and cons of snowballing sampling
pros;
ability to reach hard to access population
cons; refer within their networks
method of random sampling
lottories, random generators
pros and cons of random sampling
pros;
minimises bias
cons:
cost
response rate
application of stratified sampling
strata in the population more important to represent the groups in the same proportions
method of stratified data
divide the population into subgroups that may differ in important ways
pros and cons of stratified data
pros;
accurate representation of the subgroups
cons;
increased complexity
application of convenience sampling
using participants that are convenient to the researcher
no pattern
method of convenience sampling
asking people in their workplace, building
pros and cons of convenience sampling
pro;
cost efficient
easily acceptable
time efficient
cons:
not a good representation of the wider population
