Class 11th – Sources of Information Types | Entrepreneurship | Tutorials Point

Summary

This video explores the three main types of information sources: primary, secondary, and tertiary. Primary sources provide firsthand data collected directly by the investigator, such as interviews or surveys. Secondary sources analyze and interpret primary data, like reports or published research. Tertiary sources compile and summarize both primary and secondary data, often in the form of encyclopedias or guidebooks. The video also explains methods for collecting these types of information, with practical examples to illustrate their uses in research and everyday contexts.

Takeaways

• 😀 Primary sources are first-hand accounts or direct evidence collected by the investigator themselves.
• 😀 Examples of primary sources include surveys, interviews, autobiographies, and eyewitness accounts.
• 😀 Secondary sources analyze, interpret, or summarize primary data and are created by those without first-hand experience.
• 😀 Examples of secondary sources include biographies, encyclopedias, research articles, and government reports.
• 😀 Tertiary sources compile information from primary and secondary sources and provide an overview without in-depth analysis.
• 😀 Examples of tertiary sources include dictionaries, guidebooks, chronologies, and encyclopedias.
• 😀 Primary sources present information in its original form and are not interpreted or condensed by others.
• 😀 Secondary sources can modify or rearrange data for specific purposes, making them valuable for analysis.
• 😀 Tertiary sources are not considered credible for academic research as they lack specific authorship and in-depth analysis.
• 😀 Understanding these types of sources is essential for effective research and knowledge development.

Q & A

What are the three types of sources of information discussed in the video?

The three types of sources of information are primary, secondary, and tertiary sources.

What defines a primary source of information?

A primary source is original data collected firsthand by the investigator, presenting first-hand accounts relevant to an event without prior interpretation.

Can you provide an example of how primary information is collected?

An example of collecting primary information is going door-to-door in a neighborhood to ask residents about their preferences, such as whether they like oranges.

What are some methods of collecting primary information?

Methods include direct personal investigation, indirect oral investigation, local correspondents, mailed questionnaires, and using enumerators to gather data from informants.

How is secondary information defined in the context of the video?

Secondary information is data that analyzes, interprets, or rearranges primary data, created by individuals who did not experience the events firsthand.

What is an example of secondary information?

An example of secondary information is a report that takes census data and analyzes it to show trends, like the increase in the number of women in the workforce.

What types of sources can be considered secondary sources?

Secondary sources can include biographies, encyclopedias, historical analyses, and publications from research institutions.

What characterizes tertiary sources of information?

Tertiary sources compile and summarize information from primary and secondary sources, often used for reference and not credited to specific authors.

What are some examples of tertiary sources mentioned in the video?

Examples of tertiary sources include encyclopedias, directories, guidebooks, and other reference materials that summarize or repackage information.

Why is it important to understand the differences between primary, secondary, and tertiary sources?

Understanding these differences is crucial for conducting research effectively, as each type of source serves a unique purpose and enhances the reliability of research findings.
