Data confined to one or more selections in a series, as in a survey. The data is selected by checking a box or filling in a bubble. For example, a survey may include gender information where a respondent fills in the bubble next to an 'M' or 'F' on the survey to indicate his or her gender.
A related term is OMR or optical mark recognition, which is the software used to extract values from this type of marking.
