Sources of Secondary Data and its Advantages and Disadvantages

Data is an important element of any research. The quality of not data decides the quality of the outcome of a research. There are two types of data which a researcher uses to research on something. The two types are primary data and secondary data.

The primary data is the data which is collected first hand by the research by conducting experiments, interviews, surveys, etc. And the secondary data is the data which is not created by the user of the data but by someone else. The secondary data is as important as primary data and plays an important role in research.

Secondary data can be collected using two different research methods such as qualitative methods and quantitative methods

#1. Examples of qualitative data collection methods:

Research related documents, thesis, books, focus group transcripts, semi-structured and structured interviews, notes, field notes, research papers, etc.

#2. Examples of quantitative data collection methods:

Databases like social security, census, electoral statistics, and census, etc.

Sources of secondary data

#1. Research institutes

Research institutes research various Problems and make information collected by the public. This type of data is usually reliable and can be used for research purpose.

Research institutes like C.S.O, Indian Statistical Institute, and N.S.S.O publish data collected by them for public use.

#2. Data collected by scholars

Scholars research various research problems and publish information collected by them. This source of information is also considered a useful source of secondary data.

One most important benefit of data collected from scholar research and paper is that the data is valid and can be relied on.

#3 Government Publications

Government Publication is one of the most reliable sources of secondary data. Countries conduct research on the population for different problems and make the information collected by the public for two reasons one is to make public aware of the prevailing problems in the nation and second to let researchers use this information for further research.

There are various international organizations such as World Bank, I.M.F, world health organization (W.H.O), world trade organization (W.T.O), United Nations organization, international labor organization, world meteorological organization, food, and agriculture organization, international bank and reconstruction and development, etc.

These organizations publish data related to their organization. For example, World Bank publish information about the growth rate of different countries or the currency values and W.H.O shares information about the health status of the population of different countries and information related to the different diseases.

However, the secondary data gathered from the internet is not reliable as there is nobody which regulates or check the validity of data being uploaded on the internet.

However, one should take utmost care from choosing the platform to get secondary data to be used in research. There are plenty of authorized websites which provides secondary data on various research problem both paid and unpaid, and there are individuals who post the information that they have collected from their research on their website or blog.

The information shared by them can be useful, but it can’t be reliable. Therefore, it is important to choose the source of secondary data from the internet very carefully.

Secondary data is as important as primary data, and it has various benefits for the research. Let us learn about the advantages and disadvantages of secondary data before learning about the different sources of secondary data.

Advantages of secondary data

Secondary data is easy to use in research as other researchers have already used it.
Secondary data is easy to collect.
Other researchers collect secondary data; therefore, it is not time-consuming to colly the secondary data.
Secondary data is cost-efficient as you don’t have to spend a lot of money to conduct reserved.
Secondary data is useful for researching both small and large population samples. For example, you can get data on a large sample of the population from a government publication.

Secondary data is valid and reliable as it has already been used and evaluated by other researchers.
Secondary data ensure the correctness of data collected from primary research and helps in adding new values and attributes.
The outcomes of primary research methods can be compared with secondary data and help in research design.
Secondary data is very useful in establishing an understanding of the research problem.
Secondary data can be used to formulate and test the hypothesis of the research.

Disadvantages of using secondary data

It is difficult to collect specific secondary data related to the research problem ba hand. For example, you want information on the disposable income of people, and you get data on the gross income of people.
Secondary data which is obsolete is not useful for the research.
The accuracy of the data cannot be ensured. Inaccurate data might impact the outcome of the research.
Sometimes attributes and values collected in secondary data don’t match with the attributes and values that you want to calculate. In such scenarios, secondary data is not useful for research.
It is difficult to obtain official data.
Insufficient details about secondary data make it difficult to use for research purpose.
