As the owner of a popular clothing establishment, it came to my attention during the weekly staff meeting that customer satisfaction was a concern the employees were voicing. This discussion led to the potential of performing a survey throughout our ten locations, which serve over two-hundred customer per day. The quandary is how we build this sample.
When gathering satisfaction data from a population, such as the customers of a popular clothing store, surveys are very beneficial.
