A Pareto Chart is a type of chart that contains both bars and line graph, where individual values are represented in descending order by bars and the cumulative total represented by the line graph.A graph to identify and plot problems /defects in descending order of frequency.Principle of Pareto chart is: 80% of problems stem from 20% of the various causes.6Pareto charthome

M.Senthil Kumar12It is a graphic summary of variation in a set of data and an estimate estimate of theprobability distributionof a continuous variable(quantitative variable).A One uses thegraph to show frequency distributions. It looks very much like a bar chart.Sometimes it is said to be derived from theAncient Greek(histos) "anything set upright and(gramma) "drawing, record, writing". It is also said thatKarl Pearson, who introduced the term in 1891, derived the name from "historical diagram".

A scatter diagram is effectively a line graph with no line - i.e. the point intersections between the two data sets are plotted but no attempt is made to physically draw a line.A type ofmathematical diagramusingCartesian coordinatesto display values for typically twovariablesfor a set of data.Sometimes it is called as scatter plot or scatter graph.TQM by ...

Also called Shewhart charts or process-behavior charts, instatistical process controlare tools used to determine if a manufacturing orbusiness processis in a state ofstatistical control.The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit and a lower line for the lower control limit.TQM by ...
