What is a sample and how is it related to the population?
A sample is the subgroup or fraction of the population. It is a true representative of the population.
Differentiate between finite population and infinite population with examples.
Differentiate between finite population and infinite population with examples.
A finite population contains a finite number of units, such as the number of students in a university. An infinite population contains an infinite number of units, like the number of stars in the sky.

Study Notes
Sample and Population
- A sample is a subset of individuals or observations taken from a larger group known as the population.
- Sampling allows researchers to make inferences about the entire population based on the analysis of the sample.
Finite vs Infinite Population
- A finite population consists of a fixed number of individuals, such as all registered voters in a city.
- An infinite population refers to a group that can theoretically grow indefinitely, like the number of potential future customers for a new product.
Definition of Population
- A population is the complete set of items or individuals that share a common characteristic, such as all students enrolled in a university.
- Example of a finite population: All employees at a company, limited in number.
Population Members and Sample Units
- Population members are the individual entities or elements that constitute the population.
- Sample units are the individual elements selected from the population for analysis, such as each student enrolled in a study conducted among the university's students.
Examples of Population and Sample
- Population example: All patients in a hospital.
- Sample example: A group of 100 patients selected from that hospital for a health survey.
Sampling Unit
- A sampling unit is the basic unit of selection in a sampling process, which could be an individual, group, or element chosen from the population.
Example of a Sampling Unit
- An example of a sampling unit could be a single household within a neighborhood selected for a census survey.
Census Method in Statistics
- The Census method involves collecting data from every individual or unit in a population, aiming for complete accuracy.
Advantage of the Census Method
- The primary advantage of the Census method is its comprehensiveness, providing a complete dataset that allows for precise analysis and conclusions about the entire population.
Sampling Method in Statistics
- The Sampling method involves selecting a representative subset of the population to draw conclusions without needing data from every member, thereby saving time and resources.
