Primary data can be received first hand from things like interviews where a person collecting the data sits face to face with the respondent, while secondary data can be obtained from things like a journal and newspaper amongst others. The difference between primary and secondary data is that Primary data is collected firsthand by a researcher through experiments, surveys, questionnaires, focus groups, interviews and taking measurements, while the secondary data is readily available and is available to the public through publications, journals and newspapers. Primary data are those which are collected for a specific purpose directly from the field of enquiry, and thus original in nature. Primary data provides a statistician with detailed information. Such data are published by the authorities themselves as Government, Civil bodies, Trade Associations etc. Individuals such as Economists and institutions like Banks and other allied bodies can collect primary data for a specific purpose, by engaging trained investigators. Secondary data are such numerical information which has been already collected by some agency for a specific purpose and are subsequently compiled from that source for application in a different connection.

Numerical measures of same characteristic is known as observation and collection of observations is termed as data. Data are collected by individual research workers or by organization through sample surveys or experiments, keeping in view the objectives of the study. The data collected may be:. The difference between primary and secondary data in Statistics is that Primary data is collected firsthand by a researcher organization, person, authority, agency or party etc through experiments, surveys, questionnaires, focus groups, conducting interviews and taking required measurements, while the secondary data is readily available collected by someone else and is available to the public through publications, journals and newspapers. Primary data means the raw data data without fabrication or not tailored data which has just been collected from the source and has not gone any kind of statistical treatment like sorting and tabulation.

Primary data are fresh new information collected for the first time by a researcher himself for a particular purpose. It is a unique, first-hand and qualitative information not published before. It is collected systematically from its place or source of origin by the researcher himself or his appointed agents. It is obtained initially as a result of research efforts taken by a researcher and his team with some objective in mind. It helps to solve certain problems concerned with any domain of choice or sphere of interest. Once it is used up for any required purpose, its original character is lost, and it turns into secondary data. One must note that, even if the data is originally collected by somebody else from its source for his study, but never used then the collected data is called primary data.

COLLECTION OF DATA: MEANING OF PRIMARY & SECONDARY DATA AND DIFFERENCE BETWEEN THEM

## What is the difference between Primary and Secondary Data?

Primary and secondary data are important in information gathering may it be quantitative or qualitative. They are essential in statistical analyses and are sometimes compared with each other to verify changes. The following discussions present their respective definitions and differences. Primary data, which is first collected, is highly factual as it is the original source of the material. It utilizes a direct approach as the information is collected through naturalistic observation, experiments, focus group discussions, personal interviews, questionnaires and other first-hand methods. Thus, this kind of data is decidedly useful in studying specific and time-critical evidence.

## Difference Between Primary and Secondary Data

The data is a set of values of qualitative or quantitative variables. In statistics, the data are the individual observations. The scientific investigations involve observations on variables. Primary Data: Data collected for the first time by the original investigator. Secondary Data: The data used in statistical investigations which have already been collected by some other for their purpose and published. Primary Data Secondary Data 1 Primary data is the original data collected by the investigator.

Data is a collection of figures and facts that are meant to be used for a particular research purpose. Once there is a data set, it can be measured and analysed for various research purposes like surveying and sampling. There are two types of data — primary and secondary. Research or experiment may require either one or both forms of data. The difference between types of data becomes important as some researches require a more direct approach for gathering information whereas others require validated data or data gathered previously.

Data collection plays a very crucial role in the statistical analysis. In research, there are different methods used to gather information, all of which fall into two categories, i. As the name suggests, primary data is one which is collected for the first time by the researcher while secondary data is the data already collected or produced by others. There are many differences between primary and secondary data, which are discussed in this article. But the most important difference is that primary data is factual and original whereas secondary data is just the analysis and interpretation of the primary data.
