Sampling Techniques Flashcards
Type of sampling method that involves random selection, allowing you to make strong statistical inferences about the whole group.
Probability sampling
Type of sampling method that involves non-random selection based on convenience or other criteria, allowing you to easily collect data.
Non-probability sampling
is a sampling technique, in which the subjects of the population get an equal opportunity to be selected as a representative sample.
Probability sampling
is a method of sampling wherein, it is not known that which individual from the population will be selected as a sample
nonprobability sampling
it is the entire group that you want to draw conclusions about.
population
it is the specific group of individuals that you will collect data from
sample
it is the actual list of individuals that the sample will be drawn from.
sampling frame
the number of individuals you should include in your sample.
sample size
a type of probability sample in which every member of the population has an equal chance of being selected. sampling frame should include the whole population
simple random sampling
a type of probability sample that is similar to simple random sampling, but it is usually slighter easier to conduct. Every member of the population is listed with a number, but instead of randomly generating numbers, individuals are chosen at regular intervals.
Systematic sampling
a type of probability that involves dividing the population into subpopulations that may differ in important ways. It allows you draw more precise conclusions by ensuring that every
stratified sampling
a type of probability that involves dividing the population into subgroups, but each subgroup should have similar characteristics to the whole sample. Instead of sampling individuals from each subgroup, you randomly select entire subgroups.
Cluster sampling
are often used in
exploratory and qualitative
research
Non-probability sampling techniques
a type of nonprobability sampling method that simply includes the individuals who happen to be most accessible to the researcher.
Convenience sampling
a type of nonprobability sampling method that is mainly based on ease of
access. Instead of the researcher choosing
participants and directly contacting them,
people volunteer themselves (e.g. by
responding to a public online survey).
voluntary response sampling
a type of nonprobability sampling method that involves the researcher using their expertise to select a sample that is most useful to the purposes of the research
Purposive sampling
Another name for purposive sampling
Judgement sampling
A type of nonprobability sampling method that can be used to recruit participants via other participants. The number of people you have access to “snowballs” as you get in contact with more people.
Snowball sampling
A type of nonprobability sampling method that relies on the non-random
selection of a predetermined number or proportion of units.
Quota sampling
