Quota (Quota method)

Definition: A quota (also known as “quota method”) is a methodology applied to constitute samples within the framework of a study. The quota method ensures that the sample is representative of the population, in the format of groups of individuals meeting specific characteristics (age, sex, income, level of education, socio-professional category, political opinion, etc. .).

If the readers of a website on the world of fashion are women aged 25 to 35 aiming in urban areas and they represent 5% of the French population; then, in the context of a study on a sample of 1000 people, this quota of potential readers will represent 50 people.
