Hi Edward,

The Sample Sets is a webpart you can enable on any container.

Click on the Gear Icon > Page Admin Mode and you'll see the webpart dropdowns at the bottom of the page and then pick Sample Sets.

Sample Sets are independent of Studies, which is why that option isn't appearing in your Study Settings.

For more details and information on Sample Sets, please checkout our following docs:
