Central Composite

In statistics, a central composite design is an experimental design, useful in response surface methodology, for building a second order (quadratic) model for the response variable without needing to use a complete...

Center Points

Center points serve as fundamental concepts across mathematics, geometry, engineering, and everyday applications. Whether you’re designing architectural layouts, solving geometric problems, or planning urban developments, understanding center points becomes...

C & U charts

C & U charts are control charts for defects in quality control. In statistical quality control, the c-chart is a type of control chart used to monitor “count”-type data, typically total number of defectives per unit. It is also...

Box-Behnken

In statistics, Box–Behnken designs are experimental designs for response surface methodology, devised by George E. P. Box and Donald Behnken in 1960, to achieve the following goals: Each factor, or independent variable, is placed at one of three equally spaced values,...

Block

A Block Diagram is used to assess the effect of input variables or factors on your output (or response). First, identify any factors that could have a significant impact on your response variable. Learning how to draw a block diagram is a lot easier than it...
