Before one can present and interpret information, there has to be a process of gathering and sorting data.

Just as trees are the raw material from which paper is produced, so too, can data be viewed as the raw material from which information is obtained. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Data is collected and analyzed; data only becomes information suitable for making decision in some fashion. Gathering data can be accomplished through a primary source researcher is the first person to obtain the data or a secondary source the researcher obtains the data that has already been collected by other sources, such as data disseminated in a scientific journal Mesly, Distinguish between primary data and secondary data 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 work. 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.

While primary data is collected with an aim for getting solution to the problem at hand, secondary data is collected for other purposes.

The fundamental differences between primary and secondary data are; the term primary data refers to the data originated by the researcher for the first time while secondary data is the already existing data collected by the investigator agencies and organisations earlier. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand.

Primary data collection is a very involved process. On the other hand, secondary data collection process is rapid and easy. Primary data sources include surveys, observations, experiments, questionnaire, personal interview etc. Surveys are used in different areas for collecting the data even in public and private sectors. A survey may be conducted in the field by the researcher.

The respondents are contacted by the research person personally, telephonically or through mail. This method takes a lot of time, efforts and money but the data collected are of high accuracy, current and relevant to the topic.

When the questions are administered by a researcher, the survey is called a structured interview or a researcher- administered survey.

Observations: Observation as one of the primary sources of data. Observation is a technique for obtaining information involves measuring variables or gathering of data necessary for measuring the variable under investigation.

Observation is defined as accurate watching and noting of phenomena as they occur in nature with regards to cause and effect relation. Interviews can be undertaken on a personal one-to-one basis or in a group. Questionnaires: Questionnaire as one of the primary sources of data is an observational technique which comprises series of items presented to a respondent in a written form, in which the individual is expected to respond in writing.

Here the respondents are given list of written items which he responds to by ticking the one he considers appropriate. While secondary sources means data collected by someone else earlier. Secondary data are the data collected by a party not related to the research study but collected these data for some other purpose and at different time in the past.

If the researcher uses these data then these become secondary data for the current users. Sources of secondary data are government publications websites, books, journal articles, internal records. As opposed to secondary data which is easily accessible but are not pure as they have undergone through many statistical treatments. Creating models in psychological research.

SOURCES /METHODS OF SECONDARY DATA COLLECTION. ❑ CONCLUSION. ❑ THANK YOU. Page 3. ❑ Various methods of collecting data.

Secondary data

One of the major elements and basis of statistical research is data collection, where the most basic data that can be collected in this process is primary data. In other words, we can say that data is the basis of all statistical operations and primary data is the simplest of all data. Primary data is one of the 2 main types of data, with the second one being the secondary data. These 2 data types have important uses in research, but in this article, we will be considering the primary data type. We will introduce you to what primary data is, examples, and the various techniques of collecting primary data.

Secondary data refers to data that is collected by someone other than the primary user. Secondary data analysis can save time that would otherwise be spent collecting data and, particularly in the case of quantitative data , can provide larger and higher-quality databases that would be unfeasible for any individual researcher to collect on their own. However, secondary data analysis can be less useful in marketing research, as data may be outdated or inaccurate. Government departments and agencies routinely collect information when registering people or carrying out transactions, or for record keeping — usually when delivering a service.

Qualitative data collection methods

The data those have been collected already and readily available from other sources are called as secondary data. When compared to primary data, these secondary data are cheaper and more quickly obtainable. Usually, desk-based research is used to collect secondary data. After arriving at the secondary data, the researcher should examine the validity and reliability. Thus, the researcher should consider the secondary data which is highly valid and well-referenced in academic articles Creswell,

Home Consumer Insights Market Research. Secondary research or desk research is a research method that involves using already existing data. Existing data is summarized and collated to increase the overall effectiveness of research. Secondary research includes research material published in research reports and similar documents. These documents can be made available by public libraries, websites, data obtained from already filled in surveys etc. Some government and non-government agencies also store data, that can be used for research purposes and can be retrieved from them. Secondary research is much more cost-effective than primary research, as it makes use of already existing data, unlike primary research where data is collected first hand by organizations or businesses or they can employ a third party to collect data on their behalf.
