As Told To Secondary data is an analysis or interpretation of primary data as told to someone, with the primary data used as a basis to retell a version of the original story or present original data in a new way, as noted by Ithaca College Library.

This type of data explores, discusses and presents a fresh evaluation of original work or information provided by the original researcher or participants in an event. Secondary data is typically available to the general public via low-cost delivery modes such as magazines, newspapers and websites.

Because it typically remains available to examine for an extended time period, it can become outdated. Examples of Primary and Secondary Data A police report from an accident is a primary source, while a newspaper article about the accident is a secondary source of information.

A journal review of a scientist's research, prepared by the scientist who performed the research, is a primary source, while a magazine article explaining the scientist's paper is a secondary source. Legal documents about an event are primary sources, while a book about the event is a secondary source.

A company surveying customers about preferences and service issues is a source of primary data, while an article detailing and adding fresh insight to the survey results is a source of secondary data. Combining Primary and Secondary Data Tertiary data is a compilation of primary and secondary data. This type of data includes sources like almanacs, textbooks and instruction manuals.

The purpose of this type of compilation is to present a summary of repackaged primary and secondary data that is easier to process, notes the University of Minnesota Crookston. That allows researchers to detect change over time.

Going back to the return-to-work study mentioned above, the researchers could also examine secondary data in addition to the information provided by their primary data i.

With a combination of these two data sources, the researchers may be able to determine which factors predict a shorter work absence among injured workers. This information could then help improve return to work for other injured workers.

The type of data researchers choose can depend on many things including the research question, their budget, their skills and available resources. Based on these and other factors, they may choose to use primary data, secondary data—or both. At Work , Issue 82, Fall What researchers mean by Primary data and secondary data. Primary data An advantage of using primary data is that researchers are collecting information for the specific purposes of their study.

Secondary data There are several types of secondary data. Government publications, websites, books, journal articles, internal records etc. May or may not be specific to the researcher's need.

Primary data is data originated for the first time by the researcher through direct efforts and experience, specifically for the purpose of addressing his research problem.

Also known as the first hand or raw data. Primary data collection is quite expensive, as the research is conducted by the organisation or agency itself, which requires resources like investment and manpower. The data collection is under direct control and supervision of the investigator. The data can be collected through various methods like surveys, observations, physical testing, mailed questionnaires, questionnaire filled and sent by enumerators, personal interviews, telephonic interviews, focus groups, case studies, etc.

Secondary data implies second-hand information which is already collected and recorded by any person other than the user for a purpose, not relating to the current research problem.

It is the readily available form of data collected from various sources like censuses, government publications, internal records of the organisation, reports, books, journal articles, websites and so on. Secondary data offer several advantages as it is easily available, saves time and cost of the researcher.

But there are some disadvantages associated with this, as the data is gathered for the purposes other than the problem in mind, so the usefulness of the data may be limited in a number of ways like relevance and accuracy. Moreover, the objective and the method adopted for acquiring data may not be suitable to the current situation. Therefore, before using secondary data, these factors should be kept in mind. The fundamental differences between primary and secondary data are discussed in the following points:.

As can be seen from the above discussion that primary data is an original and unique data, which is directly collected by the researcher from a source according to his requirements.
