What is the Difference Between Population and Sample?

If we consider the general concept, ‘Population’ indicates the large group of people. In this instance, in the field of statistics population termed as a large group that consists of elements having at least one common feature. Another one is “Sample”, which is subset of the term “Population” that is selected to represent the entire group.

During the preparation of your dissertation paper,  term paper, class assignment, class presentation; you might be required  to mention the details of both the sample and population. Many students open fail to properly differences between the concept of population and sample.  Along with this, sometime they also face the very common situation, where these listed basic knowledge will play quite fruitful role to mitigate their situation. But exactly what is the main concept of population and sample letter mentioning here. Before clarifying the concept of population and sample, it’s important to know the definition of statistics, so we may begin with the definition of statistics.

### Define Statistics.

Statistics is concerned with scientific methods for collecting, organizing, summarizing, presenting and analyzing sample data as well as drawing valid conclusions about population characteristics and making reasonable decisions on the basis of such analysis

#### Sample

1 An aggregate of all individuals all items (  actual or possible) defined on some common characteristics is called population. A small but representative part with finite number or individuals or items of a population is called a sample.
2 It may be finite or infinite. It is always finite.
3 Capital letters are used to denote population size usually by N. Small letters are used to denote sample size usually by n.
4 The population size is always greater than the sample size. Sample size is always smaller than the population size.
5 Census survey deals with the population. Sample Survey deals with the  sample.
6 population is considered as the universal set. This is a subset of the population.
7 The  statistical constants of population are easily referred to as parameters . The statistical measures obtained from the sample observations has been termed as statistics .

### Conclusion

In spite of the many differences, it must be accepted that sample and population are related to each other, i.e. sample is drawn from the population. Even, the main objective of the sample is to create a statistical inferences about the population. The greater the size of the sample, the higher is the level of accuracy of generalization.
