Differences Between Primary and Secondary Data
The fundamental differences between primary and secondary data are discussed in the following points:
The term primary data refers to the data originated by the researcher for the first time. Secondary data is the already existing data, collected by the investigator agencies and organisations earlier.
Primary data is a real-time data whereas secondary data is one which relates to the past.
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 collection sources include surveys, observations, experiments, questionnaire, personal interview, etc. On the contrary, secondary data collection sources are government publications, websites, books, journal articles, internal records etc.
Primary data collection requires a large amount of resources like time, cost and manpower. Conversely, secondary data is relatively inexpensive and quickly available.
Primary data is always specific to the researcher’s needs, and he controls the quality of research. In contrast, secondary data is neither specific to the researcher’s need, nor he has control over the data quality.
Primary data is available in the raw form whereas secondary data is the refined form of primary data. It can also be said that secondary data is obtained when statistical methods are applied to the primary data.
Data collected through primary sources are more reliable and accurate as compared to the secondary sources
Answer:
What is primary data?
Primary data is the data collected for the first time through personal experiences or evidence, particularly for research. It is also described as raw data or first-hand information. The mode of assembling info is costly, as the analysis is done by an agency or an external organisation and need human resources and investment. The investigator supervises and controls the data collection process directly.
Mostly the data is collected through observations, physical testing, mailed questionnaires, surveys, personal interviews, telephonic interviews, case studies, and focus groups, etc.
What is secondary data?
Secondary data are second-hand data that is already collected and recorded by some researcher for their purpose and not for the current research problem. It is accessible in the form of data collected from different sources such as government publications, censuses, internal records of the organisation, books, journal articles, websites, and reports etc.
This method of gathering data is affordable, readily available, saves cost and time. However, the one disadvantage is that the information assembled is for some other purpose and may not meet the present research purpose or may not be accurate.

The Differences between primary data and secondary data are represented in a comparison format are as follows:
Primary Data
Secondary Data
Definition
Primary data are those which are collected for the first time. Secondary data refers to those data which have already been collected by some other person.
Originality
Primary data is original because these are collected by the Investigator for the first time. Secondary data are not original because someone else has collected these for his own purpose.
Nature of data
Primary data are in the form of raw materials. Secondary data are in the finished form.
Reliability and Suitability
Primary data are more reliable and suitable for the enquiry because it is collected for a particular purpose. It is less reliable and less suitable as someone else has collected the data which may not perfectly match our purpose.
Time and Money
Collecting primary data is quite expensive both in time and money terms. Secondary data requires less time and money so it is economical.
Precaution and Editing
No special precaution or editing is required while using primary data as these have been collected with a definite purpose. Both precaution and editing are essential as secondary data were collected by someone else for his own purpose.
