provide a way to evaluate data distribution

The matrix diagram is used to ______________.

rate the strengths of relationships between two sets of data

An interrelationship digraph is used to _______.

search for drivers and outcomes

Scatter diagrams are used to _____________.

show graphically the correlation between two variables

The tree diagram can be used to __________.

A Pareto chart _________________________.

shows the frequency or size of problems or defects in a descending bar graph

T or F: A Pareto chart is another way to show the distribution curve of a data set.

False

T or F: A cause and effect diagram captures historical knowledge but does not focus on present knowledge.

False

T or F: A good representative histogram can be made with five to seven data points.

False

T or F: You have constructed an interrelationship digraph and found a number of issues with a very close number of arrows. Although these issues must be reviewed carefully, in the end it is a judgment call, not science.
