Seven Basic Quality Tools,”Cause-and effect diagram, which are also know as fishbone diagrams. Flowcharts, which are also referred to as process maps because they display the sequence of steps and branching possibilities that exist for a process that transforms one or more inputs into one or more outputs. Check-sheets, which is known as tally sheets and may be used as a checklist when gathering data .Pareto diagram, which exist as a special form of vertical bar chart and are used to identify the vital few sources that are responsible for causing most of a problem’s effects. Histograms a special form of bar chart and are used to describe the central tendency, dispersion, and shape of statistical data. Control charts, used to determine whether or not a process is stable or has predictable performance.Scatter Diagram, plot ordered pairs (X,Y) and are sometime called correlation charts because they seek to explain a change in the dependent variable, Y
