A sample where households "or individuals" are selected in order to meet demographic (e.g. Age, social class) or other (e.g. Number of TV sets, ownership of VCR) targets. Quota sampling is the basic alternative approach to probability sampling. The critical distincion between them is that quota methods involve the fieldworkers deciding (on the basis of quotas) whether to include or discard contacted homes in the precess of sampling. The fieldworkers simply search for households that fulril their criteria. In the process, they will not necessarily work from pre-determined lists of contact addresses. The prabibilities of contact will neither be equal nor known (c.f. probability sampling above). This limits the statistical treatment of the data.
