The editing process for paper surveys involves manual checking for a number of problems, including the following: whether the interviewer failed to ask certain questions or record answers for certain questions, whether skip patterns were followed.

Coding: the process of grouping and assigning numeric codes to the various responses to a question. Coding process: list responses, consolidate responses, set codes, enter codes. After responses have been listed and consolidated and codes set, the last step is the actual entry of codes. Data entry: the process of converting information to an electronic format.
