Most of the resources in this guide focus on published surveys and studies, also known as secondary sources. The data available may not cover a particular demographic or niche industry so companies or researchers will often need to conduct their own surveys and focus groups to get feedback from their specific market for an existing or potential product or service. The resources on this page offer guidance on best practices for conducting this primary market research.
