Sampling theory is a well-researched field of statistics and its use in stereology is a fundamental building block of methods such as the optical fractionator and the.

Sampling since it is generally impossible to study an entire population (every individual in a country, all college students, every geographic area, etc), researchers typically rely on sampling to acquire a section of the population to perform an experiment or observational study. Sampling is the process of systematically selecting that which will be examined during the course of a study types of sampling approaches there are a wide range of sampling approaches. Probability sampling sampling in which each element of a population has an opportunity of being selected for the sample its purpose is to obtain a sample that is representative of the population and from which generalizations to the population can be made. Random sampling is often preferred because it avoids human bias in selecting samples and because it facilitates the application of statistics in s ystematic sampling the samples are drawn systematically with location or time, eg, every 10th box in a truck may be analyzed, or a sample may be chosen from a conveyor belt every 1 minute.

Sampling with replacement (repeated sampling) is usually considered only in theoretical investigations (an example of repeated sampling is the registration of the number of particles touching in a certain period of time the walls of a vessel within which brownian motion is under way. Sampling is the process of selecting units (eg, people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen.

Non-probability sampling schemes these include voluntary response sampling, judgement sampling, convenience sampling, and maybe others in the early part of the 20 th century, many important samples were done that weren't based on probability sampling schemes. Major types of probability sampling are: simple random sampling, stratified random sampling and cluster sampling simple random sampling a process that gives each element in the population an equal chance of being included in the sample is termed as simple random sampling.
