An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well. The distance from the mean is measured in standard deviations.
They are plotted on Levey–Jennings charts, wherein the X-axis shows each individual sample, and the Y-axis shows how much each one differs from the mean in terms of standard deviation (SD). The rules are: [2]

In statistical quality control, the ¯ and s chart is a type of control chart used to monitor variables data when samples are collected at regular intervals from a business or industrial process. [1] This is connected to traditional statistical quality control (SQC) and statistical process control (SPC).
BUENOS AIRES (Reuters) -An Argentine court dismissed aggravated rape charges against French international rugby players Hugo Auradou and Oscar Jegou on Tuesday, drawing a line under a dark period ...
The following example shows 20 observations of a process with a mean of 0 and a standard deviation of 0.5. From the Z {\displaystyle Z} column, it can be seen that X {\displaystyle X} never deviates by 3 standard deviations ( 3 σ {\displaystyle 3\sigma } ), so simply alerting on a high deviation will not detect a failure, whereas CUSUM shows ...
There is no bright-line termination standard, so it is difficult to say with certainty that a hospice deserved harsher treatment than it received in any instance. Breaking The Same Rules The 50 active hospices with the most violations since 2004, and those that were kicked off the Medicare program, were cited for many of the same violations ...
