From the matrix, one can read that knowledge of concept 1 is required in order to answer correctly questions 3, 4 and 5. One can also read that questions 1 and 2 test only the knowledge of concept 2. | From the matrix, one can read that knowledge of concept 1 is required in order to answer correctly questions 3, 4 and 5.

+ | Q-matrix can be used for understanding students' performance. Due to various knowledge and assessment characteristics, students' responses rarely match //ideal responses// generated from the matrix. Still, by assigning the closest //ideal response// to a student's response vector, it can be assumed which concepts the student does, and which he does not know. This information can be used in order to direct him in further learning. | ||
