What is a Sample Survey?
A sample survey is a research method used to collect information from a pre-selected group of people or entities. This type of survey is used to acquire data from a representative sample of a population, usually for market research or opinion polls. It can be used to gather quantitative data, such as income levels or levels of satisfaction, or qualitative data, such as opinions or beliefs.
Types of Sample Surveys
Sample surveys can be divided into three main types:
- Census Survey: A census survey collects data from all members of a population, ensuring that all members are represented in the results.
- Quota Survey: A quota survey is a survey method in which an interviewer has a predetermined number of individuals to interview in each category of the survey.
- Random Sample Survey: A random sample survey is a type of survey in which a sample of the population is selected randomly. This ensures that all members of the population have an equal chance of being selected.

Sample surveys are advantageous for a number of reasons:
