18 Questions
What is the primary purpose of using a sample in research?
To generalize the findings to the larger population
Which of the following is a key advantage of using sampling in research?
Reduced cost and time in data collection
What is the role of sampling techniques in improving the precision of research findings?
Sampling techniques help researchers select a sample that is representative of the population, minimizing bias.
What is the relationship between sampling and statistical inference in research?
Sampling provides a basis for statistical inference, allowing researchers to estimate population parameters and test hypotheses.
What is the primary difference between the target population and the accessible population in research?
The target population is the entire population of interest, while the accessible population is a subset that can be realistically studied.
Which of the following is a key consideration in selecting a sampling technique for a research study?
All of the above
What does the term 'population' refer to in the context of research and statistics?
The entire group of individuals, items, or events sharing a common characteristic of interest to the researcher
Which type of population includes the specific group of individuals or elements that the researcher is interested in studying?
Target Population
What defines the accessible population in a research study?
The subset of the target population that the researcher has access to and can feasibly study
Why is it important for researchers to define the population of interest at the beginning of a study?
To guide the sampling process and ensure relevant findings
Which population characteristic plays a crucial role in shaping research design and methodology?
Demographics
What is the main reason researchers may focus on an accessible population rather than the entire target population?
To save time and cost associated with studying the entire target population
What is the purpose of using sampling techniques in research?
To select a representative subset of the population for study
Which term refers to the complete set of individuals, items, or events that share a common characteristic and are of interest to the researcher?
Target population
What role does the population play in research studies?
Provides context for drawing conclusions and generalizations
Which characteristic of a population describes the complete set of elements that a researcher wants to study?
Scope
How does studying a well-chosen sample help researchers?
It allows for making valid inferences about the larger population
Which term refers to the boundaries of the group being studied and provides context for drawing conclusions in research?
Population scope
