Which feature allows users to analyze data specific to a defined set of user actions?

The feature that allows users to analyze data specific to a defined set of user actions is Custom Segments. Custom Segments enable you to create a subset of your data based on specific criteria that you define, such as user behavior, demographics, or technology used. This level of granularity allows you to focus on particular interactions or characteristics of users that are important for your analysis.

For example, if you want to evaluate how users who completed a specific conversion path differ from those who did not, you can create a Custom Segment that only includes users who performed certain actions, such as visiting specific pages or clicking certain buttons. This targeted analysis helps in understanding user behavior in detail and can inform marketing and product decisions.

Audience Reports provide insights into different user groups but do not allow for the level of customization in analyzing specific interactions as Custom Segments do. Event Tracking is focused on capturing interactions with content that can be defined as an event, but it does not inherently group users based on actions. Goal Conversion tracks user interactions that lead to specific outcomes but is not centered around defining user sets for comparative analysis in the same way Custom Segments are.
