Which quality tools are included in Minitab?

To detect patterns in your process data, and perform four tests for nonrandom behavior, create a run chart. In Minitab, choose Stat > Quality Tools > Run Chart.

To identify which of your process problems are most common, so that you can concentrate your improvement efforts on areas where the largest improvements can be made, create a Pareto chart. In Minitab, choose Stat > Quality Tools > Pareto Chart.

To organize brainstorming information about the potential causes of a problem, create a cause-and-effect diagram. In Minitab, choose Stat > Quality Tools > Cause-and-Effect.

To compute a range of values for a product's characteristic that likely covers a specified minimum percentage of current or future product output, create tolerance intervals. Use Tolerance intervals (Normal distribution) when your data come from a normal distribution or to calculate an interval that does not use a distribution. In Minitab, choose Stat > Quality Tools > Tolerance Intervals (Normal Distribution).

To provide analysis of variance data in graphical form, create a multi-vari chart. Multi-vari charts display up to 4 factors. In Minitab, choose Stat > Quality Tools > Multi-Vari Chart.

To provide analysis of variance data in graphical form, create variability charts. Variability charts plot standard deviations and means and can display up to 8 factors. In Minitab, choose Stat > Quality Tools > Variability Chart.

To assess whether your data come from a symmetric distribution, create a symmetry plot. In Minitab, choose Stat > Quality Tools > Symmetry Plot.
