What is Sample in Research? PPD 2 WEEK 7

A sample in research is:

• a subset of the population used to represent the entire group

• the entire population being studied

• a random selection of individuals

• a theoretical concept with no practical application

Which of the following is a method of sampling mentioned in the passage?

• Random sampling

• Systematic sampling

• Cluster sampling

• Snowball sampling

Researchers use samples in research because:

• they want to study the entire population.

• it is more practical and cost-effective than studying the entire population.

• they are not interested in the entire population.

• it is required by research guidelines.

Feasibility is an important reason for sampling in research because:

• it allows researchers to study a smaller, manageable group.

• it ensures 100% accuracy in results.

• it eliminates the need for data analysis.

• it guarantees that all variables are controlled.

How does cost-effectiveness play a role in the importance of sampling in research?

• Cost-effectiveness ensures that research can be conducted within budget constraints, making sampling a crucial method.

• Cost-effectiveness is not related to sampling in research.

• Sampling increases the cost of research, making it less cost-effective.

• Cost-effectiveness only applies to large-scale research projects.

Explain how time savings is a benefit of sampling in research.

• Sampling reduces the amount of data to be collected, thus saving time.

• Sampling increases the amount of data to be collected, thus saving time.

• Sampling has no impact on the time required for data collection.

• Sampling requires more time than collecting data from the entire population.

What is the significance of manageability in the context of sampling in research?

• It ensures the sample is representative of the population.

• It allows researchers to handle the sample size effectively.

• It guarantees the accuracy of the research findings.

• It eliminates all biases in the research process.

Representation contributes to the importance of sampling in research because it ensures that the sample accurately reflects the population being studied.

• It ensures that the sample accurately reflects the population being studied.

• It allows researchers to ignore certain segments of the population.

• It makes the research process faster and more efficient.

• It reduces the cost of conducting research.

Statistical analysis plays a crucial role in the importance of sampling in research because it:

• ensures accuracy and reliability of results

• is not necessary for small sample sizes

• only applies to qualitative research

• is only used in experimental studies

The importance of risk reduction in sampling for research is:

• To increase the accuracy of results

• To decrease the sample size

• To make the research more expensive

• To complicate the research process
