ABSTRACT:
Described is a method of determining a choice made by a user by analyzing marks made on a response sheet by the user. The method employs a response sheet having response areas in which a user is directed to make marks indicating choices. The marked response sheet is then scanned to produce a digital image and associated data of each response area. That data is analyzed for characteristics according to a set of predetermined principles. These principles are based on the form of the response areas on the response sheet. The presence of certain characteristics in the data determines whether a mark was made in the response area and whether the mark constitutes a choice by the user.
