Non-probability sampling is a sampling method that uses non-random criteria like the availability, geographical proximity, or expert knowledge of the The sampling unit may be different from the individual. Evaluating changes in soil pH and available nutrient levels over time requires that the soil samples accurately Non-probability Sampling Non-probability sampling is a type in which the sample members are not randomly selected from the population. Non-probability sampling is a sampling technique in which samples are selected based on non-random criteria, often influenced by the researcher’s judgment or convenience.

It provides Sampling is the process of selecting a sufficient number from the population so that by studying the sample, and understanding the properties or Sampling involves the collection of data on smaller number of units in comparison to complete enumeration, so the cost involved in the collection of information is reduced. These include random sampling methods, such as, simple random sampling, stratified sampling, systematic sampling, multistage sampling, cluster sampling methods (and non What are the Types of Sampling Methods?
