Primary Data: Data that has been generated by the researcher himself/herself, surveys, interviews, experiments, specially designed for understanding and solving the research problem at hand. Show
Secondary Data: Using existing data generated by large government Institutions, healthcare facilities etc. as part of organizational record keeping. The data is then extracted from more varied datafiles. Supplementary Data: A few years ago the Obama Administration judged that any research that is done using Federal Public funds should be available for free to the public. Moreover Data Management Plans should be in place to store and preserve the data for almost eternity. These data sets are published as Supplementary Materials in the journal lliterature, and data sets can downloaded and manipulated for research. NOTE: Even though the research is Primary source, the supplemental files downloaded by others becomes Secondary Source. Pros and Cons for each. Comparison Chart
Data is a collection of measurements and facts and a tool that help an individual or a group of individuals to reach a sound conclusion by providing them with some information. It helps the analyst understand, analyze, and interpret different socio-economic problems like unemployment, poverty, inflation, etc. Besides understanding the issues, it also helps in determining the reasons behind the problem to find possible solutions for them. Data not only includes theoretical information but some numerical facts too that can support the information. The collection of data is the first step of the statistical investigation and can be gathered through two different sources, namely, primary sources and secondary sources. Sources of Collection of Data1. Primary SourceIt is a collection of data from the source of origin. It provides the researcher with first-hand quantitative and raw information related to the statistical study. In short, the primary sources of data give the researcher direct access to the subject of research. For example, statistical data, works of art, and interview transcripts. 2. Secondary SourceIt is a collection of data from some institutions or agencies that have already collected the data through primary sources. It does not provide the researcher with first-hand quantitative and raw information related to the study. Hence, the secondary source of data collection interprets, describes, or synthesizes the primary sources. For example, reviews, government websites containing surveys or data, academic books, published journals, articles, etc. Even though primary sources provide more credibility to the collected data because of the presence of evidence, but good research will require both primary and secondary sources of data collection. Primary and Secondary Data1. Primary DataThe data collected by the investigator from primary sources for the first time from scratch is known as primary data. This data is collected directly from the source of origin. It is real-time data and is always specific to the researcher’s needs. The primary data is available in raw form. The investigator has to spend a long time period in the collection of primary data and hence is expensive also. However, the accuracy and reliability of primary data are more than the secondary data. Some examples of sources for the collection of primary data are observations, surveys, experiments, personal interviews, questionnaires, etc. 2. Secondary DataThe data already in existence which has been previously collected by someone else for other purposes is known as secondary data. It does not include any real-time data as the research has already been done on that information. However, the cost of collecting secondary data is less. As the data has already been collected in the past, it can be found in refined form. The accuracy and reliability of secondary data are relatively less than the primary data. The chances of finding the exact information or data specific to the researcher’s needs are less. However, the time required to collect secondary data is short and hence is a quick and easy process. Some examples of sources for the collection of secondary data are books, journals, internal records, government records, articles, websites, government publications, etc. Principle Difference between Primary and Secondary Data
Methods of Collecting Primary Data
Sources of Collecting Secondary Data1. Published Sources
2. Unpublished SourcesAnother source of collecting secondary data is unpublished sources. The data in unpublished sources is collected by different government organizations and other organizations. These organizations usually collect data for their self-use and are not published anywhere. For example, research work done by professors, professionals, teachers and records maintained by business and private enterprises. What is the data that has already been gathered?Another type of data that may help researchers is the data that has already been gathered by someone else. This is called secondary data.
Which form of data collection is less expensive?Second-hand data can add insight to a research project, and using secondary data is more efficient and less expensive than collecting primary data.
What is it called when you gather data?Data collection is the process of gathering data for use in business decision-making, strategic planning, research and other purposes.
Which type of data refers to data that has already been collected through primary resources and made readily available for researchers to use in the market research process?Secondary data means data collected by someone else earlier. Surveys, observations, experiments, questionnaire, personal interview, etc. Government publications, websites, books, journal articles, internal records etc.
