sampling

Question 1

target population

Answer 1

a real or hypothetical set of people, events, or objects to which one wishes to generalize the results.

Question 2

sample

Answer 2

a subset of people, events, or objects that are from the target population.

Question 3

random sampling

Answer 3

each sample has an equal probability of being chosen.

Question 4

non random sampling

Answer 4

not all members of the population have an equal chance of participating in the study,

Question 5

cluster sampling

Answer 5

you divide a population into clusters, such as districts or schools, and then randomly select some of these clusters as your sample

Question 6

convenience sampling

Answer 6

a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand.

Question 7

intact sampling

Answer 7

a type of non-probability sampling used to produce results that can be generalised only by making very strong assumptions about the sample(s). An intact group is an already-formed group (e.g., church groups, political organisations, or classrooms of students).

Question 8

systematic sampling

Answer 8

a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval

Question 9

volunteer sampling

Answer 9

when researchers seek volunteers to participate in studies.
