Stratification: A technique that separates data gathered from a variety of sources so that patterns can be seen (some lists replace stratification with flowchart or run chart). Scatter diagram: Graphs pairs of numerical data, one variable on each axis, to look for a relationship. Pareto chart: A bar graph that shows which factors are more significant. Histogram: The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). Quality pros have many names for these seven basic tools of quality, first emphasized by Kaoru Ishikawa, a professor of engineering at Tokyo University and the father of "quality circles."
