Ordinal Bin

Purpose

The ordinal bin interface allows ordinal data to be assigned to nodes. The participant drags nodes into an appropriate "bin" to assign the value.

Configuration

Each prompt defines a variable, whose value identifies an entry in the variable registry. The valid options for the ordinal value are defined in that variable registry entry.

See also the General Interface API.
