Without any information, you will not know the latest info and cannot solve various kinds of problems. And without the data that was sought beforehand, there would be no such thing as information and solutions to everyday problems. However, it is unfortunate in reality that many people do not understand the function and how important data is for today’s life.
And on this occasion we will review more deeply about the definition or understanding of data, functions and various types of data that we usually encounter everyday.
The term data is actually not only found in the field of computer only, but in almost all aspects of life such as research, education, social and others. Immediately, a more complete review of the meaning of data can be seen below:
Basically the data is a collection of information or descriptions of a matter obtained through observation or searching to certain sources. The data obtained can be an assumption or fact because it has not been processed further. After being processed through research or experiments, the data can be in a more complex form such as a database, information or even a solution to a particular problem.
In terms of language the word “data” is taken from the word “datum” which in Roman is defined as something given. Therefore, the real definition of data is given, not giving, because if you give, the data has become standard information and is recognized as true. The term data is indeed more commonly found in the computer field or within the scope of a research.
In the field of computers, you must be familiar with the name database or data processing software. While in the scope of research, it has become mandatory that every researcher must first look for data by doing research observation (observation) before being studied further and finally the research results are obtained. It is also often found in field of education such as journaling or thesis writing.
After understanding the definition of data, it is clear that the function of the data itself is clear. Maybe the term data is heard more in the field of computers or research, but basically in almost all aspects of your life you need this so-called data.
For researchers a data is used as the main basis in their research. In use computer field It also almost always involves data which is then processed to solve problems.
By looking at the above, it can be concluded that a data serves to make the best decisions in solving problems, can be used as the basis of a plan or research, used as a reference in any research. implementation an activity and finally the data can also be used as evaluation material. A data can be likened to a basis for planning or a history of all actions that have been taken. This is why almost all aspects of life involve data.
Types of Data
Because there are almost all aspects of life, it is not surprising that data can be grouped into several types. There are many parameters for grouping data but most of them may be grouped based on their nature, based on the source or where the data comes from, based on the time of retrieval and many more.
1. Based on the source
Previously, it was discussed that a data was obtained from a different way of obtaining. This difference in sources can also classify data into several types, namely primary data and secondary data.
- Primary data or this original data is obtained from certain sources obtained by the object of research.
- Secondary data or additional data is usually obtained from previous sources such as books, journals and others.
2. Based on its properties
A data can also be distinguished based on its properties, namely: qualitative data and quantitative data. These two types of data are also often used in various research opportunities that have been carried out before
- Qualitative data usually found in the form of verbal statements, pictures or even symbols.
- Quantitative data more directed to statements in numbers or numbers.
3. Based on the pick-up time
Furthermore, a data can also be grouped based on the time of collection or collection. There are types of data collected periodically and cross section data.
- Periodic data This can be found in population survey activities, data needs population in the last year.
- Cross section data or data collected at a certain time such as data on student exam results obtained after the exam is completed.
Actually, if discussed more deeply, there are still many parameters for grouping a data such as based on composition, ratio and many more, but the three parameters above are often encountered in the community.
After reading the article regarding the meaning of data that we made above, it can be concluded that data has indeed become a basic need for the community.
However, it is very unfortunate that in reality there are still many people who do not understand the definition of a data or even understand but try to misuse the use of data. Therefore, we hope that readers will be aware of this and can make maximum use of the data obtained.
