## 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.
