b) Tree diagram
c) Matrix Data Analysis diagram
d) Relationship diagram

Explanation: Matrix Data Analysis diagram is the only new seven management tool that uses numerical data and produces numerical results. It is also known as MDAC. It is different from the matrix diagram where symbols are used to indicate the strength and existence of a relationship.

3. Matrix Data Analysis diagram is used in ‘Principle Component Analysis’.
a) True
b) False

Explanation: Matrix Data Analysis diagram is used in ‘Principle Component Analysis’. It is one of the new seven management tools. The other new management tools are affinity diagram, relationship diagram, tree diagram, matrix diagram, decision tree, and arrow diagram.

4. In a matrix data analysis diagram, two different brands are compared. Brand 1 is having the coordinates (40,6) and Brand 2 is having the coordinates (40,-6). X-axis is the cost of the item and Y-axis is customer satisfaction. Which brand would you prefer?
a) Brand 2
b) Brand 1
c) Both are equally preferred
d) Can’t be determined

Explanation: Brand 1 and Brand 2 have the same x-component i.e. 40. So, the cost of the item is equal for both the brands. But, Brand 2 has a negative y-component i.e. -6 whereas Brand 1 has a positive y-component i.e. 6. So, Brand 1 has a positive customer satisfaction and Brand 2 has a negative customer satisfaction. Therefore, Brand 1 is preferred.
