How to Create a Control Chart for Seasonal or Trending Data
Posted on March 25, 2009 Comments (1)
Lynda Finn, President of Statistical Insight, has written an article on how to create a control chart for seasonal or trending data (where there is an underlying structural variation in the data). Essentially you need to account for the structural variation to create the control limits for the control chart. She also provides a Minitab project file. Both are available for download from the Curious Cat Management Improvement Library.

Hello Intrested in getting some information regarding seasonal trending. Worked with Winter’s Method, but looking to see if there are any other tools associated with Minitab?
Thank you for your time.
