How to interpret pareto chart in minitab
Minitab is a statistical software package that automates the calculation of Pareto charts. Enter the categories of defects into Minitab in the form of a column. If, for example, you wanted to create a Pareto chart of problems you are having with your cell phone, your data would look like this: How to Create a Pareto Chart in Minitab. What’s a Pareto Chart? A Pareto Chart is a quality chart of discrete data that helps identify the most significant types of defect occurrences. It does this by showing both frequency of occurrences (bar graph) and cumulative total of occurrences (line graph) on a single chart. Of course, if you're using Minitab, the software will do all this for you automatically—create a Pareto chart by selecting Stat > Quality Tools > Pareto Chart or by selecting Assistant > Graphical Analysis > Pareto Chart. You can collect raw data, in which each observation is recorded in a separate row of your worksheet, or summary data, in which you tally observation counts for each category. When you create a Pareto chart in our statistical software, your data must include the names of each defect. These names can be text or numeric. These names can be text or numeric. If your data are summarized in a table, you must include a column of frequencies or counts, with nonnegative numeric values for each defect. The Pareto chart shows the absolute values of the standardized effects from the largest effect to the smallest effect. The standardized effects are t-statistics that test the null hypothesis that the effect is 0. The chart also plots a reference line to indicate which effects are statistically significant. Interpreting a Pareto Chart. The left vertical axis of the Pareto chart has "counts" or "cost" depending on the data used. Each vertical bar represents the contribution to the total from a given "problem" area.
13 Mar 2017 When Do You Use a Pareto chart? While Pareto charts can be highly effective, they are only useful for certain types of data, namely, hypothetical
Reducing the largest bars identified in the diagram will do more for overall improvement than reducing the smaller ones. There are two ways to analyze Pareto Step 1: Examine the order of the bars. A Pareto chart is a bar chart in which the bars are ordered from highest frequency of occurrence to lowest frequency of occurrence. Use a Pareto chart to rank your defects from largest to smallest, so that you can prioritize quality improvement efforts. Download and open the Pareto Chart.MTW data file. Click on Stat → Quality Tools → Pareto Chart. A new window with the title “Pareto Chart” pops up. Select “Category” into the “Defects or attribute data in” box. Select “Count” into the box “Frequency in.”. Click “OK.”. The Pareto Chart will open in a new window. Minitab is a statistical software package that automates the calculation of Pareto charts. Enter the categories of defects into Minitab in the form of a column. If, for example, you wanted to create a Pareto chart of problems you are having with your cell phone, your data would look like this:
Interpreting the results The analysis of variance table gives a summary of the main effects and interactions. Minitab displays both the sequential sums of squares (Seq SS) and adjusted sums of squares (Adj SS). If the model is orthogonal and does not contain covariates, these will be the same.
Thank you for a sublime explanation for the 80/20 rule which I first heard 45 years ago then again 10 years ago.

Interpreting a Pareto Chart. The left vertical axis of the Pareto chart has "counts" or "cost" depending on the data used. Each vertical bar represents the contribution to the total from a given "problem" area. Then select the column of data that has the frequencies of the defects from the white box -- in this example, the “C2 Occurrence” data. Double-click on the words “C2 Occurrence” to put these terms into the “Frequencies in” box. Click on the “OK” button with your left mouse button. Minitab will produce the Pareto chart.
