One finds multiple choice processes (multiple selection, voting procedure answers) in use in the field of education and in public opinion research : on the one hand, in tests and examinations at universities and other schools and on the other, in opinion trends and attitudes in surveys and market research situations.
Multiple choice formats offer various pre-formulated answers and assessment possibilities to a question or statement. Selection is made by manually marking the corresponding answer or rating, usually by inserting a cross or ticking or blackening a box preceding one of the answers or ratings with a pencil or ballpoint pen.
Optical mark readers recognize these marks on exam forms, questionnaires and polarity profiles and pass on the marking coordinates to a PC. The application software interprets the marks that were made, analyzes them and then very quickly and reliably calculates the test results, survey ratings or queried attitudes. The findings can subsequently be imported directly into databases.
In cases in which a statutory archiving obligation is required, high-performance scanners or OMR/scanner hybrids simultaneously prepare a digital image of the filled in test form or similar document for digital storing.
