What is the most cost-effective method for acquiring data from a large dispersed group of users?

The most cost-effective method for acquiring data from a large dispersed group of users is through the use of questionnaires. This approach allows for the collection of data from numerous individuals simultaneously, regardless of their geographical location.

Questionnaires can be distributed electronically, which significantly reduces the costs associated with paper, printing, and travel compared to other methods. Furthermore, they can be designed to capture quantitative data through structured questions or qualitative feedback through open-ended prompts, making them versatile for different data collection needs.

The efficiency of questionnaires is also enhanced by the ability to swiftly analyze responses using software tools, which can compile results in real-time, aiding in quicker decision-making processes. Additionally, the anonymity that questionnaires often provide may lead to more honest and considered responses from participants.

In contrast, methods such as interviews or case studies typically involve more resources and time due to the need for one-on-one interaction and in-depth exploration of topics. Workshops may also require gathering participants in a single location, increasing logistical costs and limiting participation to those who can attend.
