Dealing With Count-Based Data: Which Chart Do I Choose?

When dealing with quality data, it is common to be presented with data that deal with counts, or attributes.  This immediately raises the question, what is the most appropriate way to chart these data?  In this seminar, we will discuss the characteristics of count-based data, the various charts that are available, the pros and cons of each, and an alternative that may surprise you.  Topics will include:

  • Characteristics of count-based data
  • A brief history of the charts for count-based data
  • The p-chart, the np-chart, the c-chart, and the u-chart, and when to use each one
  • Is there a better way?
