Question 5

Which statement is not true about judgmental sampling?

A) It does not allow direct generalizations to a specific population. 
B) It may be useful if broad population inferences are not required. 
C) Each population element has a known and equal probability of selection.

 B)False

Question 7

Sample size is influenced by the average size of samples in similar studies.

Accepted Answer

A) True 
 B)False

Question 9

Which of the following conditions does not favor the use of a sample (Table 11.1 in the text)?

Accepted Answer

A) There are budget and time limit constraints. 
B) The population is large. 
C) The cost of nonsampling errors is high. 
D) The cost of sampling errors is high.

Question 10

Accepted Answer

A) True 
 B)False

Question 11

There are several basic questions involved in sampling design. "Should a sample be taken? If so, what process should be followed?" are two such questions. Which of the following questions is also involved in sampling design?

Accepted Answer

A) What kind of sample should be taken? 
B) How large should the sample be? 
C) What can be done to control and adjust for nonresponse errors?

Accepted Answer

A) stratified sampling 
B) systematic sampling 
C) cluster sampling 
D) area sampling

Question 13

Stratified sampling differs from quota sampling in that the sample elements are selected probabilistically rather than based on convenience or judgment.

Question 14

Convenience sampling is the least expensive and least time consuming of all sampling techniques.

Accepted Answer

A) True 
 B)False

D) Simple random sampling

Question 16

Accepted Answer

A) convenience sampling 
B) cluster sampling 
C) quota sampling 
D) snowball sampling
