How are Matrices Used to Represent Data? Matrices is an outstanding concept to represent data if your data is related to each other in an adjacent manner. For instance, let us consider the marks of different subjects that you study in your class. Almost every student study the same subjects; however, each student may get different marks in each of those subjects. A matrix would allow us to keep track of all of this and make it easier to perform calculations that without the matrix would be cluttered. You can think of a matrix like a graphic organizers for large amounts of data. These worksheets and lessons introduce students to using matrices as a method of representing data. We explain the why and how.
