Sometimes primary data cannot be obtained or it becomes difficult to obtain primary data, in such cases the researcher is bound to use secondary data.
Sources of secondary data[ edit ] Secondary data can be obtained from different sources: This information is called administrative data. It is a regularly occurring and official count of a particular population.
It is a type of administrative data, but it is collected for the purpose of research at specific intervals. Most administrative data is collected continuously and for the purpose of delivering a service to the people.
Advantages and disadvantages of secondary data[ edit ] Secondary data is available from other sources and may already have been used in previous research, making it easier to carry out further research.
It is time-saving and cost-efficient: Administrative data and census data may cover both larger and much smaller samples of the population in detail.
Information collected by the government will also cover parts of the population that may be less likely to respond to the census in countries where this is optional. The data may have been used in published texts and statistics elsewhere, and the data could already be promoted in the media or bring in useful personal contacts.
Secondary data generally have a pre-established degree of validity and reliability which need not be re-examined by the researcher who is re-using such data. Secondary data can provide a baseline for primary research to compare the collected primary data results to and it can also be helpful in research design.
However, secondary data can present problems, too. The data may be out of date or inaccurate. If using data collected for different research purposes, it may not cover those samples of the population researchers want to examine, or not in sufficient detail.Secondary data is one type of quantitative data that has already been collected by someone else for a different purpose to yours.
For example, this could mean using.
Secondary data in research consists of several sources. Sometimes primary data cannot be obtained or it becomes difficult to obtain primary data, in such cases the researcher is bound to use secondary data.
Secondary Research is of value when information is compared and analyzed, when the researcher performs a critical review of the data, and when the researcher comes up with actionable findings to move the project forward. Examples of secondary data are research reports, government reports, censuses, weather reports, interviews, the Internet, reference books, organizational reports and accounting documents.
Secondary data can be defined as information collected by someone other than the user. What are the sources of Secondary Data? Collection of Secondary Data The secondary sources can be classified into two categories via.
Published and unpublished sources. Individual research scholars collect data to complete their research work which further is published with their research papers. Secondary Data Collection Methods Definition: When the data are collected by someone else for a purpose other than the researcher’s current project and has already undergone the statistical analysis is called as Secondary Data.
