Question: What feature or filter can help you investigate why two videos of the same length have different audience retention metrics?
- Filter.
- Comparison.
- Groups.
- Date range.
Explanation
Comparison lets two videos be reviewed side by side in YouTube Analytics. This helps isolate differences in retention patterns even when video length is the same. Audience retention can vary because viewers may drop off at different moments within each video. Comparing videos directly makes it easier to identify where performance diverges.
Why the other options are incorrect
Filter narrows visible data but does not directly compare two videos side by side.
Groups combine selected content for aggregate reporting, which is not the best fit for investigating two individual videos.
Date range changes the reporting period but does not explain retention differences between two videos.
