Shewhart individuals control chart. In statistical quality control, the individual/moving-range chart is a type of control chart used to monitor variables data from a business or industrial process for which it is impractical to use rational subgroups. [1] The chart is necessary in the following situations: [2]: 231.
The control limits are set at three standard deviations on either side of the process mean, and are known as the upper control limit (UCL) and lower control limit (LCL) respectively. [2] If the process data plotted on the control chart remains within the control limits over an extended period, then the process is said to be stable. [2] [3]
Lifting condensation level. Schematic of the LCL in relation to the temperature (T) and dew point and their altitude (Z); the moist adiabatic temperature curve above the LCL is also sketched for reference. The lifting condensation level or lifted condensation level (LCL) is the height at which the relative humidity (RH) of an air parcel will ...
The importance of knowing the natural process variation becomes clear when we apply statistical process control. In a stable process, the mean is on target; in the example, the target is the filling, set to 1 litre. The variation within the upper and lower control limits (UCL and LCL) is considered the natural variation of the process.
x̅. and s chart. 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).
x̅ and R chart. x̅. and R chart. In statistical process control (SPC), the and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process.

FMA. 38866. Anatomical terminology. [edit on Wikidata] MRI of the elbow (T1 weighted) showing an unimpaired radial collateral ligament and extensor tendon. The radial collateral ligament (RCL), lateral collateral ligament (LCL), or external lateral ligament[Explain 1] is a ligament in the elbow on the side of the radius.
Anatomical terminology. [edit on Wikidata] The ulnar collateral ligament (UCL) or internal lateral ligament is a thick triangular ligament at the medial aspect of the elbow uniting the distal aspect of the humerus to the proximal aspect of the ulna.
