The main difference between primary and secondary data is that the primary data is factual and original. While Secondary data is the result of the analysis and interpretation of primary data.
Data collection is a stage in the research process that is important, because only by obtaining the right data then the research process will take place until the researcher get an answer from the formulation of the problem that has been established.
The Data we are looking for should be the following research objectives. With the correct sampling technique, we’ve got the strategies and procedures we’ll be using in search of the data in the field. In this section, we will discuss it.
What is Primary Data?
Primary data is a source of data obtained directly from the source (not through intermediate media). It can be individual or group opinion of a subject (person), observation of an object (physical), event or activity, and test results.
Methods to collect the primary data
- Physical testing
- Email sending to respondents
- Fill in questionnaires
- Personal interview
- Interview via phone
- Case studies
- Focus Group Discussion/FGD.
The process of collecting primary data is also known to be quite expensive compared to secondary data (depending on the scope of the research), as well as taking a long time to be a weakness of primary data.
What is Secondary Data?
Secondary data is a source of research data that researchers obtain indirectly through intermediate media (acquired and recorded by others). Secondary data is generally evidence, records or historical reports that have been arranged in archives (documentary data) that are published and unpublished. Secondary data can be obtained more easily and quickly because it is already available.
This data is a form of data that has been available from various sources, such as:
- Census results
- Government/private publications
- Internal records of an organization
- Report documents
- Journal articles
- Websites from trusted institutions and so on.
Before the search process of secondary data is done, we need to identify the need first. Identification can be done by making the following questions:
- Do we need secondary data in resolving the issues to be researched?
- What kind of secondary Data do we need? Identifying the secondary data we need will help accelerate in search and time saving and cost.
Advantages of Secondary Data
Understanding the problem
Secondary Data can be used as a supporting means to understand the problems we are going to be thorough. For example, if we will research a company, the company provides company profiles or other administrative data that we can use as a trigger to understand the issues that arise in the company and Which we will use as a research problem.
Explanation of the problem
Secondary Data is beneficial to clarify the problem and become more operational in the research because it is based on the available secondary data, we can know the components of the environmental situation that Surrounding it.
It will be easier for researchers to understand the issues to be researched, especially gaining a better understanding of experiences similar to the issues that will be examined
Alternative formulation of proper problem solving
Before we make a decision, sometimes we need some other alternative.
Secondary Data will be useful in raising some other alternative that support in resolving the problem that will be researched. With the increasing amount of information we get, then the problem is to be a lot easier.
Secondary Data Besides benefiting from helping to define and develop problems, secondary data can sometimes bring up solutions to existing problems. Not infrequently the problem we will be careful will get the answer based only on secondary data only
Main difference between primary data and secondary data
- Primary data relates to data derived from first-time researchers. In contrast, secondary data is data that has been collected by previous researchers could be an institution/agency/organization/person.
- Primary data is factual or real-time data. While secondary data is data relating to the past.
- The primary data collection process is a process that requires full involvement in the field and it takes time. On the other hand, the process of collecting secondary data is relatively quick and easy.
- Primary data collection sources including, surveys, observations, experiments, questionnaires, interviews, and others. While the sources of secondary data collection are, books, publications from the Government/private, journal articles and others.
- Primary data collection requires great resources such as time, cost, and labor. Conversely, secondary data is relatively cheaper and faster in the data collection process.
- Primary Data is always specific to the needs of researchers, and you as a researcher control the quality of research. Unlike secondary data is not specific to the needs of researchers, and also has no control over data. Because researchers as hands to two.
- Primary data is available in raw data form while secondary data is a subtle form of primary data. It can also be said that secondary data is obtained when a statistical method is applied to primary data.
- Data collection through major sources is more reliable and accurate, unlike secondary data.
