Skosmos: SamplingProcedure-1.1: Non-probability: Quota

Nonprobability.QuotaNon-probability: Quota

The target population is subdivided into separate and mutually exclusive segments according to some predefined quotation criteria. The distribution of the quotation criteria (gender/age/ethnicity ratio, or other characteristics, like religion, education, etc.) is intended to reflect the real structure of the target population or the structure of the desired study population. Non-probability samples are then drawn from each segment until a specific number of units has been reached. For example, if the target population consists of 45 percent females and 55 percent males, a proportional quota sample will have the same gender percentages, while in a non-proportional quota sample the percentages will be different, based on some study-related consideration (for instance, the need to oversample for certain under-represented segments of the population).
