Research Methodology II

Why is it important to collect data from a variety of sources?

• To ensure data accuracy and reliability

• To save time and resources

• To avoid data redundancy

• To simplify data analysis

What are the advantages of collecting primary data from individuals?

• It provides first-hand information.

• It is less time-consuming.

• It is less expensive.

• It is more reliable.

What are the disadvantages of collecting data solely from individuals?

• Limited perspective

• Bias in data

• Lack of generalizability

• All of the above

How can groups and organizations be sources of primary data?

• By conducting surveys and interviews

• By analyzing secondary data

• By reviewing literature

• By using existing databases

What are the advantages of using print sources for data collection?

• Print sources are easily accessible.

• Print sources provide reliable information.

• Print sources are cost-effective.

• Print sources are up-to-date.

What are the disadvantages of using digital sources for data collection?

• Data privacy concerns

• High cost of data storage

• Limited access to technology

• All of the above

Reliability in the context of data collection refers to:

• The consistency of a measure

• The accuracy of a measure

• The validity of a measure

• The relevance of a measure

What does it mean when it is said that reliability is estimated?

• It refers to the consistency of a measure.

• It indicates the accuracy of a measure.

• It shows the validity of a measure.

• It means the measure is reliable.

What is the definition of validity in research?

• The degree to which a result is accurate and free from bias

• The extent to which a test measures what it claims to measure

• The consistency of a research study or measuring test

• The ability to generalize findings to a larger population

What is the relationship between reliability and validity?

• Reliability refers to consistency, while validity refers to accuracy.

• Reliability and validity both refer to the accuracy of a measurement.

• Reliability refers to accuracy, while validity refers to consistency.

• Reliability and validity are unrelated concepts.
