Guttman Scale

The Guttman scale is a type of measurement used to assess attitudes or knowledge in a hierarchical way. In the context of general knowledge, it organizes questions from simple to complex. For example, if someone answers a basic fact correctly, they may also know more advanced facts related to that topic. This method helps researchers understand how knowledge accumulates and indicates a person's depth of understanding. If a participant answers a harder question correctly, it typically implies they can also answer the easier ones, reflecting a progressive level of knowledge.
