On this page, we compare different Exponentially Weighted Moving Average (EWMA) control chart is one of the control charts used to detect a small shift in the mean process. In the quality control
To create a moving average chart, choose Stat > Control Charts > Time-Weighted Charts > Moving Average. When to use an alternate control chart The EWMA chart is generally preferred over the Moving Average chart because the EWMA chart weights the observations and each plotted point on the EWMA chart takes all of the previous observations into account.

The Moving Average Control Chart is a time-weighted control chart that is constructed from a basic, unweighted moving average. It is often advisable to use the moving average control chart when you desire to quickly detect a change or shift in the process since it is more sensitive to shifts in the process than the traditional average and range control chart (i.e., X-bar and R ).
16 Nov 2018 Roberts [1] proposed the exponentially weighted moving average (EWMA) control charts, which are useful in detecting the smaller shift in the 15 Oct 2017 Chapter 8.

Moving Average / Range Charts are a set of control charts for variables data (data that is both quantitative and continuous in measurement, such as a measured dimension or time). The Moving Average chart monitors the process location over time, based on the average of the current subgroup and one or more prior subgroups. The Moving Range chart monitors the variation between the subgroups over time.

The name was changed to reflect the fact that exponential smoothing serves as the basis of EWMA charts. • Like a cusum chart, an EWMA chart is an alternative to The Moving Average Charts procedure creates control charts for a single numeric variable where the data have been collected either individually or in subgroups.

The Moving Average Control Chart is a time-weighted control chart that is constructed from a basic, unweighted moving average. It is often advisable to use the moving average control chart when you desire to quickly detect a change or shift in the process since it is more sensitive to shifts in the process than the traditional average and range control chart (i.e., X-bar and R ). The moving average/moving range chart (MA/MR) is used when you only have one data point at a time to describe a situation (e.g., infrequent data) and the data are not normally distributed. The MA/MR chart is very similar to the Xbar-R chart. The only major difference is how the subgroups are formed and the out of control tests that apply.
