Final answer:
Vaughan's study on uncoupling did not include observation of divorce court proceedings but likely used online surveys, interviews, and analysis of divorce statistics to gather data.
Step-by-step explanation:
The study in question appears to be based on the methodologies used by researchers in social studies, particularly within the field of sociology. From the information provided, it seems that Vaughan did not utilize observation of divorce court proceedings as a method to find participants for her study on uncoupling. Instead, Vaughan likely used methods such as online surveys and questionnaires, interviews with divorced individuals, and analysis of divorce statistics. These methods are prevalent in research on individual behaviors, beliefs, and experiences, as they can yield large amounts of data and allow for the exploration of in-depth, subjective information that individuals may not comfortably reveal in a more public or observable setting.
