20 Questions
What is the target universe in research sampling?
The universe that the researcher wants to reach
What does a sample represent in research sampling?
A finite part of the universe chosen for study
What is the process of drawing units from the universe for sampling called?
Sampling
In order for a sample to represent the universe well enough, what is one of the key requirements?
Appropriate sample size
What is the accessible universe in research sampling?
The concrete universe that the researcher can reach
What is the main concern with convenience sampling?
It may not represent the entire population
How is stratified sampling different from simple random sampling?
Stratified sampling ensures proportional representation of subgroups
What is the key limitation of outlier sampling?
It may lead to biased results
What is the purpose of systematic sampling?
To select units randomly from the universe list
What distinguishes probabilistic sampling methods from non-probabilistic sampling methods?
Probabilistic methods involve randomness in the sample selection process
Which of the following best defines the target universe in research sampling?
The universe that the researcher wants to study, which may be difficult to access but reflects the ideal choice
What does a sample represent in research sampling?
A specific part of the universe chosen for detailed study
What distinguishes probabilistic sampling methods from non-probabilistic sampling methods?
The use of random selection in probabilistic methods
What is the main concern with convenience sampling?
The potential bias in sample selection
How is stratified sampling different from simple random sampling?
In stratified sampling, the population is divided into subgroups and then units are randomly selected within each subgroup
What is the main difference between probabilistic and non-probabilistic sampling methods?
The use of random selection in probabilistic methods
What distinguishes stratified sampling from simple random sampling?
Stratified sampling aims to represent subgroups in proportion to their weight, while simple random sampling does not consider subgroup representation
What is the main concern with convenience sampling?
Low representative power of the sample to represent the universe
What is the purpose of outlier sampling?
To create a sample from contradictory (extreme) situations related to the problem
What distinguishes systematic sampling from simple random sampling?
Systematic sampling involves selecting every Kth element from the sample frame, while simple random sampling does not have a systematic process
