Deck 13: Sampling

Question 1

Snowball sampling and judgment sampling are both non-probability sampling techniques.

Answer 1

True

Question 2

Probability sampling is seen as less representative for the population than non-probability sampling.

Answer 2

False

Question 3

Which of the following sampling designs is a form of non-probability sampling?

A)Systematic sampling.
B)Area sampling.
C)Quota sampling.
D)Cluster sampling.

Answer 3

C

Question 4

The bigger the sample size,the better.

Question 5

Convenience sampling and quota sampling are examples of probability sampling.

Question 6

In probability sampling all elements of a population have a known and equal change to be included in the sample.

Question 7

Simple random sampling is a method associated with a high degree of generalizability.

Question 8

What is the least reliable and least efficient probability sampling technique?

A)Systematic sampling.
B)Proportionate stratified sampling.
C)Disproportionate stratified sampling.
D)Cluster sampling.

Question 9

If your objective is to compose a representative sample,what kind of sampling technique would you choose?

A)Simple random sampling.
B)Judgment sampling.
C)Convenience sampling.
D)Quota sampling .

Question 10

When representativity is an important criterion for a study,which sampling technique would you choose?
a.Systematic sampling.
b.Judgment sampling.
c.Quota sampling.
d.Convenience sampling.

Question 11

If a sample is subdivided into subsamples,a minimal sample size of 30 is necessary for every subsample.

Question 12

Non-probability sampling leads to findings that are highly generalizable.

Question 13

From statistical considerations the preference is given to probability sampling over non-probability sampling.

Question 14

Cluster sampling is the least representative probability sampling design.

Question 15

Based on the desired accuracy and reliability of the research results,we can determine a desired sample size by a formula.The desired sample size is adjusted (and we then speak of an adjusted n)when:

A)The sample size is greater than 1000 persons.
B)The sample size is greater than 50 percent of the population.
C)The sample size is greater than 1 percent of the population.
D)None of the above answers is correct.

Question 16

With systematic sampling one divides the population into subgroups and chooses the test subject randomly from a number of randomly chosen subgroups.

Question 17

If a sample is subdivided into subsamples,a minimal sample size of 10 is necessary for every subsample.

Question 18

Snowball sampling and Quota sampling are both non-probability sampling techniques.

Question 19

As a rule,probability sampling leads to a representative sample.

Question 20

Stratified sampling and cluster sampling are examples of probability sampling.

Question 21

A researcher wants to investigate the relationships between the use of drugs and study results of university students.He would like to generalize the results to the population.Which kind of sample could the researcher best use?

A)Stratified sampling
B)Judgment sampling
C)Simple random sampling
D)Quota sampling
