2.2 Random Sampling vs Quota Sampling
Random sampling is when respondents are picked randomly, whereas quota is picked from a group of people with specific characteristics
Random uses pre-selected respondents who must be asked to take part in the research,, whereas Quota allows researcher to find respondents who fit the characteristics required
Random is expensive to carry out because specific respondents must be interviewed and contacted until they are available, whereas Quota is less expensive as the interviewer simply needs to find suitable respondents
Random sampling reduces biased results because of method of selection of respondents, whereas bias can occur with quota sampling as the interviewer decides who to question
