Quota Flashcards
This method of sampling is often used by market researchers.
Quota sampling
Interviewers are given a quota of subjects of a specified type to attempt to recruit.
Quota sampling
For example, an interviewer might be told to go out and select 20 adult men, 20 adult women, 10 teenage girls and 10 teenage boys so that they could interview them about their television viewing.
Quota sampling
Ideally the quotas chosen would proportionally represent the characteristics of the underlying population.
Quota sampling
For example: A researcher wants to survey indiiduals about what smartphone brand they prefer to use. He/she considers a sample size of 500 respondents.
Also, he/she is only interested in surveying ten cities in Cebu. Here’s how the researcher can divide the population by quotas:
: Age: 100450 moles ane 250 been the ages of 16-20, 21-30, 31-40, 41-
50, and 51+
: Employment apus sue need a qu150 Ploy peopthe 150
unemployed people, 100 must be students.)
• Location: 50 responses Der citu
Quota sampling
While this has the advantage of being relatively straightforward and potentially representative, the chosen sample may not be representative of other characteristics that were not considered.
