How to Organize Survey Data

I'm running a survey for a class project, and in this survey, the user has the ability to check multiple items (in this case, features they think would be important to a campus map system). The items have number labels on a separate document (but if necessary can be changed to letter labels) to make things easier to organize. Is there a way to have Excel sort these items by popularity (ie, most frequently selected items)? 

The column in question is "Q13"
