Imagine you’re reviewing your website’s analytics and notice a large percentage of users exiting the site on the third step of your conversion funnel. The third step of the conversion funnel is the “product comparison page.” You want to review the behaviors and interactions each user has on that page just before they exit. Which research category would be best to use in the scenario above?

Observational research is best because it involves directly watching users interact with the product comparison page in real-time or through recordings (like heatmaps or session recordings). This allows you to see their exact behaviors, clicks, scrolls, and hesitations just before they exit, providing direct insight into their struggles. Qualitative research is too broad; while observation is a qualitative method, "qualitative" itself doesn't specify the direct behavioral focus needed here. Quantitative research focuses on measurable data (e.g., bounce rates, time on page) but won't show why users are leaving. Prototyping is about creating early versions of a design, not analyzing current user behavior.
