Seven Statistical Tools Overview

Course Duration: 1 Day - 8 Hours/day

This one-day seminar provides training on the seven statistical tools. These tools are used in problem solving and continual improvement endeavors. The seven statistical tools were first introduced by Dr. Ishikawa when he introduced problem solving in Japan. Dr. Ishikawa put together seven simple tools that were already available for use. While the entire tool set is not named after him, the cause and effect diagram or the fishbone diagram which has been attributed to his creation has often been also called the “Ishikawa” diagram. When using the seven statistical tools, it is always good to remember Dr. Ishikawa’s words to those doing improvement – “speak with data”. Omnex teaches this course as a standalone one day or in conjunction with our problem solving courses.
