## Double Matrix Method

Summary

The Double Matrix Method is a powerful tool for solving complex set problems where each member of a population is classified in two distinct ways, such as by gender and education level.

- Introduces the concept of classifying a population by two variables simultaneously, using gender and education level as examples.
- Explains how to organize information using the Double Matrix Method, which involves creating a matrix with rows and columns representing the different categories of each variable.
- Demonstrates the method through a problem involving employees classified by gender and education, showing how given information leads to the deduction of unknown data.
- Expands on the method's application to more complex scenarios, including problems with three categories for one variable and the use of percentages.
- Highlights the method's utility in simplifying problems by systematically organizing data to find relationships and solve for unknowns.
