The design that involves an in-depth exploration of a single unit of study is known as a case study design. This method allows researchers to gather comprehensive and detailed information about a specific individual, group, organization, or event, providing insights that may not be obtainable through broader approaches. Case studies are particularly valuable in healthcare and nursing settings, where understanding the complexities of a patient's experience or a particular phenomenon can lead to improved clinical practice and patient outcomes.

This design typically employs various data collection methods such as interviews, observations, and review of records, fostering a rich understanding of the subject matter. By focusing intensively on one unit, researchers can identify unique patterns, challenges, and solutions that might be overlooked in larger sample studies.

Other research designs mentioned serve different purposes: event-partitioning design focuses on identifying and categorizing events, trend design examines changes over time within a population, and cross-sectional design captures a snapshot of information from various subjects at a single point in time. These designs do not provide the same depth of understanding about a single unit as a case study does.
