Data collection II: methods Flashcards
how is data collected?
in a number of ways, from diverse sources - can use one or a few data collection methods
what is triangulation?
a process in which multiple collection methods of data are used
what do qualitative researchers do?
make sense of feelings, experiences, social situations or phenomena in their natural setting
what is aimed for when collecting qualitative data?
minimal interference/interruption within the context
engage with participants in an open and empathetic manner
what are the steps involved in the data collection process?
obtaining ethical clearance
obtain permission and access through gatekeepers
sampling
data collection
what is sampling?
the selection of research participants from an entire population
what are the types of sampling?
probability and non-probability sampling
what is probability sampling?
all members of a population stand an equal chance of being selected for the study
what is non-probability sampling?
the selection of participants is not determined by the statistical principle of randomness
what does sampling involve questions about?
which people to sample
which setting to sample from
what are the types of probability sampling?
convenience sampling, purposive sampling and snow-ball sampling
what is convenience sampling?
recruiting people who are easily available and accessible
what is purposive sampling?
recruiting people who have experienced the phenomenon/research problem being studied
what is snow-ball sampling?
recruiting participants through existing contacts
why does qualitative research not require large sample sizes?
focus on in-depth, detailed explanations
sample size determined by approach to research
what is theoretical saturation?
when new cases no longer provide new information - data collection stops
how can the decision of how many cases to study be informed?
whether it is a new or developed area of study
how much detail one is likely to gather in one case
budget and time constraints
what are some sampling strategies?
maximum variation, critical case sampling, confirming or disconfirming cases, theoretical sampling
what is maximum variation sampling?
when seeking the broadest range of perspectives on the subject of study
what is critical case sampling?
looking for data that is information rich
what is confirming or disconfirming sampling?
seeking to confirm of disconfirm an emerging analytical account
