SAMPLING PRELIM Flashcards

1
Q

The process to SELECTING THE SAMPLE. When you conduct research about a group of people, it’s rarely possible to collect data from every person in that group.

Q

SLOVIN’S FORMULA FOR SAMPLE SIZE

A

n = N / (1+Ne2)
n = sample
N = Population
1 = Constant
e = margin of error (e = 0.05 (5%) )

Q

EVERY MEMBER OF POPULATION has an EQUAL CHANCE OF BEING. Your
sampling frame should include the whole population.

Q

EVERY MEMBER OF POPULATION has an EQUAL CHANCE OF BEING. Your
sampling frame should include the whole population.

A

Simple random sampling

17
Q

similar to simple random sampling, but it is USUALLY SLIGHTLY 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.

A

Systematic sampling

18
Q

involves DIVIDING THE POPULATION INTO SUBPOPULATIONS that may differ in important ways. It allows you draw more precise conclusions by ensuring that EVERY SUBGROUP is properly represented in
the sample.

A

Stratified sampling

19
Q

involves DIVIDING THE POPULATION INTO SUBPOPULATIONS that may differ in important ways. It allows you draw more precise conclusions by ensuring that EVERY SUBGROUP is properly represented in
the sample.

A

Stratified sampling

20
Q

also 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.

A

Cluster sampling

21
Q

INDIVIDUALS ARE SELECTED BASED ON NON-RANDOM CRITERIA, and not every individual has a chance of being included.

A

Non-probability sampling

22
Q

simply includes the individuals who happen to be MOST ACCESSIBLE TO THE RESEARCHER. It can be RISK FOR BOTH SAMPLING BIAS and selection bias.

A

convenience sample

23
Q

simply includes the individuals who happen to be MOST ACCESSIBLE TO THE RESEARCHER. It can be RISK FOR BOTH SAMPLING BIAS and selection bias.

A

convenience sample

24
Q

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).

A

Voluntary response sampling

25
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
26
KNOWN AS JUDGMENT SAMPLING, involves the researcher using their expertise to select a sample that is MOST USEFUL TO THE PURPOSES OF THE RESEARCH. An effective purposive sample must have clear criteria and rationale for inclusion.

Purposive sampling
28
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.
