Methodology Flashcards
We use this on how we are going to collect data from respondents
Research Design and data collection
The entire group that you want to draw a conclusion about
It may be defined in terms of geographical location, age, income, etc.
Population
Specific group of individuals that you will collect data from
Sampling
List of indiviuals that the sample will be drawn from
Sampling frame
Should include the entire target population
Sampling Frame
Number of individuals in your sample, depends on the size of the population and how precisely you want the results to represent the population as a whole
Sample Size
The larger it is, the more accurately and confident you can make inferences about the whole population
Sample size
Every member has an equal chance if being selected
Kinds of probability sampling
Simple random sampling
Should include whole population.
Kinds of probability sampling
Simple random sampling
The population is randomly selected at regular
intervals, with all members having the chance
to be chosen, but not all will be selected to
participate.
Kinds of probability sampling
Systematic sampling
Involves division of a population to a smaller
group
Kinds of probability sampling
Stratified Sampling
Divides the population into subgroups with
similar characteristics to the whole sample,
and selecting entire subgroups randomly
instead of sampling individuals from each
subgroup.
Kinds of probability sampling
Cluster Sampling
Includes the individuals who happen to be
most accessible to the researcher
Kinds of non-probability sampling
Convenience Sampling
Relies on ease of access, with participants
volunteering themselves through public online
surveys instead of being chosen and contacted
by the researcher.
Kinds of non-probability sampling
Voluntary Response Sampling
Researchers use judgement to select the most
useful sample for their research purposes,
aiming to gain detailed knowledge about a
specific phenomenon rather than making
statistical inferences.
Kinds of non-probability sampling
Purposive Sampling
