Which Chart is Right?When tracking data over time, you have a number of options. You could use a P-chart, designed specifically to track mortality or adverse health events over time. You could use an X-bar chart designed for tracking averages over time, e.g. average health status or satisfaction ratings of a group of patients. You could use a moving average chart to help you construct control chart for an individual patient's data over time. You can use XmR charts or Tukey charts or many other methods of analyzing the data. This section helps you decide which of these various charts are appropriate for your application. We ask you 4-7 questions and based on your answers advise you which chart is right for the application that you have in mind. Question: Have you collected observations over different time periods?
