The CRC aims to gather feedback from the population of interest. However, to collect feedback from the entire population is extremely costly and can take a lot of time.

Another option is to collect information from a sample of the population. Sampling, when carried out correctly, collects feedback from a sample that is representative of the larger population.

There are several types of sampling designs that can be used depending on the population and information to be collected. To select and apply the accurate design for your CRC, previous knowledge of statistics and experience in developing a sampling plan is necessary. You must consult an expert on sampling techniques.
