Guttman Scalogram

A Guttman Scalogram is a method used to measure people's responses to a set of statements or questions, especially in areas like general knowledge. It organizes items in a way that reflects increasing levels of agreement or knowledge. For example, if someone knows the capital of a country, they likely know the country’s name. Each person’s responses can then be arranged to indicate their overall knowledge level, showing patterns that help researchers understand how knowledge builds from simpler to more complex concepts. This approach helps in assessing how well someone understands a subject.
