Certainly, the primary method of data collection is costly. Observations, surveys, questionnaires, polling, focus groups, oral histories, etc. are some of the commonly used methods. Being first-hand data sources, they are costlier than secondary sources. If you precisely want to know which primary method is the costliest, data collection services providers consider questionnaire is so. It is just because you need experts to create a set of attractive questions that target audience can easily understand and would like to reply or respond. Once created, it requires extraction. This part is also a standalone process, which involves a particular cost. All in all, its cost is based on the efforts and skills involved in this process.
