HistogramA histogram is a type of bar graph which displays a range of data that has been grouped into certain classes. Scatter DiagramsThe scatter diagram is a diagram where the relationship between two characteristic values are plotted on a graph paper and analyzed as to whether a correlation exists between the 2 sets of data.This analysis of correlation will enable you to take the necessary steps to control and improve the required process.

This order is then expressed with the bar graph.Ĭause and Effect DiagramThe cause and effect analysis which was first developed by Professor Kaoru Ishikawa of the University of Tokyo in the 1940s, is also known as the Fishbone Diagram or the Ishikawa DiagramThis tool is a picture of lines and symbols designed to represent the relationship between the effects as problems and the causes influencing them. To draw this diagram, the problems need to be first categorized according to phenomenon or causes such as defects and corrections, before data is collected and arranged in order of the number of defects or the number of corrections. The details Pareto DiagramThe Pareto Diagram is a bar graph with a cumulative curve connecting the different points.

Benkei owned 7 weapons, which he used to win all his battles. The term 7 tools for QC is named after the 7 tools of the famous warrior, Benkei. Welcome toProblem Solving Through7 QC TOOLS
