#1
Which of the following is NOT a probability sampling method?
Convenience sampling
ExplanationConvenience sampling is a non-probability sampling method.
#2
In cluster sampling, the population is divided into:
Clusters
ExplanationCluster sampling divides the population into distinct clusters.
#3
Which sampling method involves dividing the population into non-overlapping groups based on certain characteristics?
Stratified sampling
ExplanationStratified sampling divides the population into distinct characteristic-based groups.
#4
Which sampling method involves selecting every kth element from a list?
Systematic sampling
ExplanationSystematic sampling selects every kth element from a list.
#5
What is a characteristic of simple random sampling?
It ensures every member of the population has an equal chance of selection
ExplanationSimple random sampling ensures equal chances of selection for all population members.
#6
Which sampling method is most appropriate when the population is large and widely dispersed?
Cluster sampling
ExplanationCluster sampling is effective for large and dispersed populations.
#7
What is the disadvantage of using systematic sampling?
It may introduce bias if there is a pattern in the list
ExplanationSystematic sampling may introduce bias if there's a pattern in the sampling list.
#8
Which sampling method is commonly used in market research?
Quota sampling
ExplanationQuota sampling finds common use in market research.
#9
What is the purpose of stratified sampling?
To ensure proportional representation of subgroups
ExplanationStratified sampling aims to ensure proportional subgroup representation.
#10
What is the primary limitation of convenience sampling?
It may introduce bias
ExplanationConvenience sampling's primary limitation is its potential bias introduction.
#11
Under which circumstances is quota sampling most useful?
When the population is heterogeneous
ExplanationQuota sampling is advantageous for heterogeneous populations.
#12
What is an advantage of using stratified sampling over simple random sampling?
It ensures better representation of population subgroups
ExplanationStratified sampling provides better representation of population subgroups compared to simple random sampling.
#13
What is an advantage of cluster sampling?
It is cost-effective
ExplanationCluster sampling is cost-effective.
#14
What is an advantage of using systematic sampling?
It ensures every member of the population has an equal chance of selection
ExplanationSystematic sampling ensures equal chances of selection for all population members.
#15
What is a limitation of quota sampling?
It may introduce bias if the quotas are not representative
ExplanationQuota sampling may introduce bias if quotas aren't representative.
