Guttman Procedure

The Guttman Procedure is a method used in survey design to measure attitudes or knowledge levels, especially in general knowledge tests. It involves creating a series of questions that increase in difficulty, where a person's ability to answer correctly is measured cumulatively. If someone answers a harder question correctly, they are presumed to have the knowledge needed for the easier ones. This approach allows researchers to gauge not just what a person knows but also the depth of their understanding. The results help in analyzing patterns of knowledge and creating more effective assessments.
