1. Introduction

The X-bar chart is a type that is used to monitor the arithmetic means of successive samples of constant size, n. This type of control chart is used for characteristics that can be measured on a continuous scale, such as weight, temperature, thickness, etc.

As the above sample X-Bar Chart example suggests, the x-bar and R-chart are quality control charts used to monitor the mean and variation based on samples taken in a given time. The control limits on both chats are used to monitor the mean and variation of the process going forward. You can use EdrawMax Online to create X-Bar Charts for your project.

The X-bar chart is a sort of Shewhart control chart used in industrial statistics to monitor the arithmetic means of successive samples of constant size, n.
