1. Problem Solving Unit 1 Lesson 1
Objective: 1.01a Select or create a graphical display for a given set of data.
TLW: Use a matrix diagram to solve problems
Essential ?: How do I set up the matrix diagram and how do I know where to start?

2. When are matrix diagrams used?
A typical use of the Matrix Diagram to compare two lists is where the list on the left represents a problem (the 'what') and the list above represents a solution to that problem (the 'how'). For example, the first list details customer requirements for a product, whilst the second list shows how this is translated into design specifications. The relationship values now can be used to identify specific problems and other points of interest.

5. The Problem:
Fred, Kent, Allie, and Jane (two sets of siblings) each have a favorite sport: running, biking, swimming and golf. Given the following clues, construct a matrix to help determine who likes which sport. Fred hates golf. He agrees with Mark Twain that golf is nothing but a good walk spoiled. Kent wouldn’t run around the block if he didn’t have to, and neither would his sister. Each sisters favorite sport is featured in a triathlon. Allie bought her brother a new bike for his birthday to use in his favorite sport.

6. Ask Yourself What events am I comparing and how many are there?
Is there anything I can cross out right away?
If it helps make a list of what you know and what you need to know.
