5 Questions
What is sampling and why is it important in research?
Sampling refers to the method or process of selecting respondents from a population. It is important in research as it allows researchers to derive facts and evidence to support the claims or conclusions propounded by the research problem.
What are the different types of probability sampling mentioned in the text?
The types of probability sampling mentioned in the text are not provided.
What are the different types of non-probability sampling mentioned in the text?
The types of non-probability sampling mentioned in the text are not provided.
Define the terms 'respondents' and 'population' as used in the text.
Respondents are subjects who are expected to answer questions to yield data for a research study. Population refers to the bigger group from where respondents are selected.
How can researchers employ sampling techniques in their research papers?
Researchers can employ sampling techniques in their research papers by using them to select respondents and derive facts and evidence to support the claims or conclusions of the research problem.
Study Notes
Understanding Sampling in Research
- Sampling is a research methodology used to select a subset of individuals or cases from a larger population to make inferences about the entire population.
Types of Probability Sampling
- Simple Random Sampling: Each individual in the population has an equal chance of being selected.
- Stratified Sampling: The population is divided into subgroups or strata, and random samples are drawn from each stratum.
- Systematic Sampling: Every nth individual is selected from the population list.
- Cluster Sampling: The population is divided into smaller groups or clusters, and a random sample of clusters is selected.
Types of Non-Probability Sampling
- Convenience Sampling: Participants are selected because they are easily accessible.
- Purposive Sampling: Participants are selected based on their expertise or knowledge.
- Snowball Sampling: Existing participants refer others who meet the study's criteria.
- Quota Sampling: Participants are selected based on predetermined characteristics.
Key Research Terminology
- Respondents: Individuals who participate in a study and provide data.
- Population: The entire group of individuals or cases that a researcher is interested in understanding or describing.
Employing Sampling Techniques in Research
- Researchers can use sampling techniques to draw inferences about a larger population based on a smaller, representative sample.
- Sampling techniques can help reduce costs, increase efficiency, and improve data quality in research studies.
