You want to conduct a survey on the popularity of Noodles among the students of different schools in your town. How would you design and choose your sample of study? Give reasons in support of your answer.

Answer 1

In order to select a sample for the survey to be conducted for assessing the popularity of noodles, quota sampling method can be used. Under this method, the entire population would be divided into different groups according to various characteristics such as the school to which the student belongs, age group, etc. The required sample would then be selected from different groups. For example, suppose the sample is to collected from 100 children from 10 schools. The investigator can further decide that out of these 100 children 40% would be in the age group 5-10 and 60% in age group 10-15. The selection of the required sample for the interview within the quota would then be at the discretion of the investigator.
