It is collecting an unrepresentative "slice" of data that leads to inaccurate conclusions.
It is the graph used to show the relationship or correlation between two factors or variables.
It defines the boundaries of the process; clarifies specifically where the start and end points for improvement reside, defines where and what to measure and analyze and needs to be within the sphere of control of the team, working on the project.
