NONPROBABILITY Meaning and
Definition
-
Nonprobability is a term used in statistics and research methodology to describe a type of sampling or data collection method that does not rely on random selection. It is an approach that does not involve probability theory, where every member of the population has an equal chance of being selected for the sample. Nonprobability sampling methods are often employed when conducting studies on populations that are difficult to reach or when traditional random sampling is not feasible or practical.
In nonprobability sampling, the selection of individuals or elements to be included in the sample is not based on randomness, but rather on the researcher's discretion or convenience. This means that the resulting sample may not represent the entire population accurately, as certain segments or individuals might be overrepresented or underrepresented.
Nonprobability methods include convenience sampling, where individuals are selected based on their easy accessibility; purposive or judgmental sampling, where participants are deliberately chosen because they possess specific characteristics relevant to the research; and snowball sampling, where existing participants refer or recruit other potential participants.
Nonprobability sampling can be useful in exploratory research, when a deep understanding of a particular subgroup or phenomenon is desired. However, it is important to acknowledge the limitations and potential biases associated with nonprobability sampling methods, as they may introduce selection bias and affect the generalizability of the findings to the larger population.

Etymology of NONPROBABILITY
The word "nonprobability" is derived from combining the prefix "non-" meaning "not" or "lack of" with the word "probability".
The prefix "non-" comes from the Latin word "non" meaning "not" or "lack of". Probability, on the other hand, originates from the Latin word "probabilitas", meaning "quality of being provable or demonstrable". It is formed from the root word "probabilis", which means "likely" or "credible".
Thus, "nonprobability" combines these elements to indicate the absence or lack of probability, often used in the context of research methodology and statistical analysis to refer to methods that do not rely on random sampling.
