Pareto Charts: A key element of a pareto chart is the cumulative line graph which shows the percent contribution of all preceding bars. This helps determine how much each bar or combination of bars represents of the problem. Unfortunately, most SPC software packages miss the point. The pareto charts created by these applications don't display the cumulative percentages at all or display them in a manner that is hard to correspond to the graph.

Box and Whisker Plots: A key element of a Box and Whisker Plot is the outliers. Outlier points are those that are greater than 1.5 times (Q3-Q1). Again, most SPC Sofware packages omit these from their Box and Whisker Plots.

What People are Saying...

I have been a fan and advocate for QI Macros for about as long as you have been in business. For the past 10 years I have been an ISO 9000 Consultant and use QI Macros for my data analysis and have had most of my customers buy QI Macros. All of my customers are small companies, QI Macros meets and exceeds their needs at a fraction of the costs of a Mintab or other similar products.
