This video takes a quick look at the results for an open card sort. It doesn't go into great detail on any particular aspect of the process but if you'd like more information, just send a request to firstname.lastname@example.org.
The survey demonstrated in this video is for a fictional online supermarket, similar to the example survey which you can try out on the OptimalSort homepage.
The video was made before UI changes, so your version will look different.
