In a study, both qualitative research and quantitative research, secondary data and primary data are things or information that must exist. With this data, you can see a broad picture of the situation being studied.
As previously said, data itself is an important component of research. The data is divided into two types according to the method of collection.
So, on this occasion, we will discuss in more detail about primary data.
Primary Data Is..
Primary data is a source of research data obtained from the original source directly. To obtain information, researchers must conduct direct interviews with informants. This is the result of observing an object based on opinions from groups or individuals.
Later the results of these observations will affect the test results in the form of objects. If seen from the definition above, it can be concluded that researchers need to collect data by survey method (research question and answer) and can also be by observation method (object research).
The advantage possessed by primary data is that the resulting data shows more truth based on what the researchers heard and saw directly. So that the existence of various elements of lies from invalid sources can be avoided.
However, the drawback of primary data is that it takes a relatively long time to conduct surveys and observations. In addition, meeting and conducting questions and answers directly with the resource person also requires a relatively large amount of money.
Characteristics of Primary Data
Each data in a study of course has its own characteristics or characteristics. For the primary data itself, there are several characteristics that are not shared by various other data. Immediately, here are some characteristics possessed by primary data types.
1. Original and Factual
The first characteristic of primary data is original and factual, where the data is actually taken from a trusted source. Data retrieval is also carried out directly, so the results of the methods used are truly original without any engineering.
2. Valid and Accurate
Still related to the characteristics of the previous primary data, this survey and direct observation will produce valid and accurate data. Researchers can also hear answers from sources directly without going through any intermediaries.
3. Need a lot of human resources
As previously said, the methods used to collect primary data are surveys and observations. This means you need a lot of human resources to create good primary data.
4. Huge Cost
To carry out surveys and observations on all the human resources that have been collected, of course you need to pay a lot of money. Mainly to reimburse the costs that were sacrificed by the interviewees in order to take part in the survey.
5. Long Time
In addition to the high cost, the process of collecting primary data also requires a lot of time. What’s more, if there are many informants participating in the data collection process, the time needed to produce the primary data will be even longer.
Differences between Primary Data and Secondary Data
Even though they have read some of the characteristics of primary data as above, some are still confused about the difference between primary data and secondary data. If you are also still confused, just look at the differences between primary data and secondary data which will be explained below.
Actually, the difference between primary data and secondary data can be understood from the concept. Primary data is raw data or collected by taking data directly in the field.
Meanwhile, secondary data is a variety of data used by researchers to complement the previous data. This secondary data was obtained from journals, reports, books, to sites on the internet. So just in the initial concept, the two research data already have significant differences.
For primary data, its nature refers more to data that continues to grow over time or what is often referred to as real-time. Even though it is accurate and reliable, this primary data cannot be used in the future, especially after changes have been made.
As for secondary data, it is usually related to data that existed in the past. So the nature of this type of research data remains. You can still use it anytime, because there is no time limit.

3. Collection Process
Primary data is collected by involving researchers together with active participants. The process of collecting primary data is usually through several activities such as observation, surveys, questionnaires, interviews and other media in the field.
Meanwhile for secondary data, the collection process tends to be faster and easier to do. Researchers only need to utilize various data that can be obtained from several sources such as the internet, open books, journals, and so on.
Then for specifications, primary data is always specific in adjusting to the various needs of researchers. Usually this primary data can determine or control the quality of the research results at the end. This relates to the authenticity of primary data that cannot be faked.
On the other hand, secondary data is not very specific to the needs of the researcher. This secondary data also does not have any control to determine the quality of the data. Only as additional data to complement the existing data.
With this, the combination of primary data and secondary data will enable researchers to obtain more complete information. Observations will be carried out more broadly if more information is obtained.
The form of primary data and secondary data is of course also different. Usually primary data is available in unprocessed form. So this primary data is still completely raw and there has been no improvement at all.
As for secondary data, it is generally in the form of data that has been compiled and also processed. This makes the results of the data more perfect and tidy. Even so, it is not uncommon for secondary data to be obtained from primary data that has previously been processed using statistical methods.
So, the difference between primary data and secondary data is the level of accuracy. In terms of accuracy, you could say that the level of accuracy of primary data is much higher. This is because primary data is collected from original data in the field.
Meanwhile, secondary data is relatively inaccurate because it has undergone several stages of analysis or processing beforehand. With this, the primary data is often the main data that can be relied upon.

However, the existence of secondary data also cannot be ruled out, because this data will complement the research data. Secondary data can also provide a new perspective on the object of observation. So, these two data have strengths and an important role.
