Definition of POPULATION & SAMPLE Along with Examples [LENGKAP]

Definition of Population

In general, understanding of population is a group or group of living things that have the same characteristics or characteristics (species the same which lives in the same geographical region or area at a certain time, and is able to reproduce among these living creatures.

In other terms, there are also those who suggest that the population is a group or group of residents or residents in a particular area, whether human, animal or plant in a certain place.

So it can be concluded that the notion of population is a set of objects (such as humans, other living things, objects, symptoms , or events) that have the same characteristics and are in the same place or space.

Understanding Population According to Para Experts

 understanding of population is

In addition to the above explanation of the definition of population, there are also some experts who express their opinions regarding the notion of population. The following are some expert opinions on the definition of population, namely:

1. Hadari Nawawi

According to an expert named Hadari Nawawi, argues that the notion of population is everything that concerns all objects of research which includes such people, animals, plants, objects, symptoms, events, or also values a test that became a data source that has certain characteristics or characteristics in a study.

2. Margono (2004)

According to an expert named Margono, said that the population is all data that is the center of attention of a researcher in a predetermined time and scope. Population is closely related to data. If everyone has data and provides a data, then it could be that the number of populations will be as much as there are humans.

3. Mohammad Nazir (2005)

According to an expert named Mohammad Nazir, argues that the population is a group or group of individuals who have the qualities and character set by the researchers. Quality or characteristics are given variable names. According to him the population is divided into 2 types, namely the finite population and the infinite population.

4. Suharsimi Arikunto

According to an expert named Suharsimi Arikunto, said that population is defined as the whole object or subject of research. If there is a researcher who wants to examine and observe all the elements contained in the area or area of ​​his research, the designation for his research is population research.

5. Sugiyono (2008)

According to an expert named Sugiyono, said that the population is a region of generalization which includes objects or subjects that have certain qualities and characteristics that have been determined by a researcher to be investigated and observed and later a conclusion will be drawn from the study.

Population Types

 Population Types

Populations have various types. In general, the population can be categorized into 3 types, namely based on number, nature, and other differences. The following is an explanation of several types of population, namely:

1. Based on Total Population

Population types based on population are further divided into 2 types, namely:

  • Limited Population is a population that has a source of data that can be easily counted because the limits are clearly quantitative. For example, in 1980 there were 3 million women who took part in the KB program (Family Planning) .
  • Infinite Population is a population that has resources that cannot be counted and expressed in terms of numbers because the data doesn't have a number of restrictions. For example, the number of prisoners in Indonesian prisons is very large.

2. Based on the Nature of Population

Population based on the nature of the population is further divided into 2 types, namely:

  • Homogeneous populations are populations in which the elements have the same properties, so the numbers do not need to be quantitated. Heterogeneous is a population in which the elements have various characteristics, so boundaries must be established both quantitatively and qualitatively.

3. Based on Other Differences

Population types based on other differences are further divided into 2 types, namely:

  • Target Population is a type of population that has been determined and determined according to research problems.
  • Population Survey is the type of population involved in the research carried out.

Definition of Samples

In general, the definition of a sample is a part of the characteristics and amounts possessed by that population, or is small parts taken from members of the population based on certain procedures so that it can represent the population.

If a population is large enough, and researchers will not be possible to study and examine everything contained in the population, this is due to limited funds, energy and time, therefore the researcher can use samples taken from the population. Samples to be taken and later to be used from the population must be truly representative or able to represent. If the state of the subject or object in the population is truly homogeneous, then a new sample can be done.

Because of the vast population that takes up a lot of costs, time and energy. Therefore, research samples must be used. In the research sample enough to use a few small pieces of the population. So this can save you the use of energy, time and costs.

Researchers need not hesitate to take many samples. A sample whether large or small in the size of the study will not be determined by the population, but expressed by the quality of implementation, theoretical basis, and management.

Definition of Samples According to Experts

 Understanding of Samples According to Experts [19659003] In addition to the above explanation of the general understanding of the sample, there are also some experts who expressed their opinions about the understanding of samples. The following are some opinions of experts who expressed their opinions, namely:

1. Sugiyono (2008: 118)

According to an expert named Sugiyono, said that the sample has meaning from a part of all the characteristics possessed by a population. If the data from a population is large enough, it will make it difficult for researchers to study and examine all that is in the population.

Then there will be several obstacles that will be faced namely energy, limited funds, and time, therefore samples will be needed in this case that will be taken from the population. Then, the researcher will study and examine the sample and will produce a conclusion that will be used for the population.

2. Arikunto (2006: 131)

According to an expert named Arikunto, argues that the definition of a sample is partially or is a representative of the population to be studied and studied. If a study examined is part of the population, then the research is arguably a sample study.

3. Nana Sudjana and Ibrahim (2004: 85)

According to experts named Nana Sudjana and Ibrahim, said that the sample is a portion of the population that can be reached and is the same as the population of the sample taken.

4. Sukmadinata (2013: 250)

According to an expert named Sukmadinata, said that the sample is a small group that is studied and studied and will draw conclusions from the population.

5. Sabar (2007)

According to an expert named Sabar, argues that samples are part of the object or population subject that is studied and studied, which certainly can represent the population representative.

Population and Sample Examples

 sample population and sample

Examples of populations and samples, for example, when voting surveys during elections. Both surveys are conducted when vote counting or quick count times or also during surveys conducted before the election.

In the survey conducted both carried out by the Indonesian 1945 Survey Institute or Saiful Mujani Research & Consulting, or Population and so on, they always conduct surveys by using quantitative research techniques in population use and samples.

Existing survey institutions take several samples using certain methodologies or techniques and the results obtained are not much different from the results of reality. really is. Population retrieval techniques and samples are carried out in order to save the costs needed and facilitate the process.

In this case, if a conclusion is taken, the population should be surveyed by all Indonesians, but in fact there are only a few [1945932] people were only sampled in the survey conducted.

Thus was the discussion in this article about the definition of population, as well as understanding the sample and also the sample population and sample. Hopefully you can better understand and understand what the population and sample are. Hopefully this article can be useful. Thank you 🙂
