Q

type of probability sampling (4)

A

simple random sampling
cluster sampling
systematic sampling
stratified random sampling

15
Q

every member of the population has an equal chance of being selected

A

simple random sampling

16
Q

divides the population into subgroups, but each subgroup should have similar characteristics to the whole sample

A

cluster sampling

17
Q

Instead of sampling individuals from each subgroup, you randomly select entire subgroups

A

cluster sampling

18
Q

every member is listed with a number, but instead of randomly generating numbers, individuals are chosen at random intervals

A

systematic sampling

19
Q

appropriate when the population has mixed characteristics, and you want to ensure that every characteristic is proportionally represented in
the sample

A

stratified random sampling

20
Q

Divide the population into subgroups (called strata) based on the relevant characteristics (e.g. gender, age range, income bracket, job role)

A

stratified random sampling

21
Q

in order to draw conclusions about the population from the sample, it must assume the sample is representative of the population

A

non-probability sampling

22
Q

a convenience sample simply includes the individuals who happen to be most accessible to researcher

A

convenience sampling

23
Q

this involves the researcher using their judgment to select a sample that is most useful to the purposes of the researcher

A

judgmental or purposive sampling

24
Q

method in which researchers choose individuals according to specific traits or qualities they decide and create quotas
so that the research samples can be useful in collecting data

A

quota sampling

25
Q

research participants recruit
other participants for a test
or study

A

snowball sampling
