04 PARETO ANALYSIS
In the fourth Minitab tutorial, we will see how the quality team at Smartboard Company uses a Pareto analysis to examine its delivery performance. In this Minitab tutorial, we will first understand how a Pareto chart is basically structured, and what information it provides us with. As part of our Pareto analysis, we will then get to know a number of other useful options, for example to quickly retrieve dispersion and location parameters or how we can perform arithmetic operations using the calculator function. We will learn, how to generate a pie chart and a histogram, and also understand for example, how the class formation is calculated in the histogram. As part of the Pareto analysis, we will also learn, how to assign continuously scaled data to categorical value ranges, and how we can individually code these value ranges to create the Pareto diagram. In addition, we will also learn about data extraction by using corresponding function commands.
