Main Effects Plot

A main effects plot is a graphical representation that displays how different levels of an independent variable affect the dependent variable while averaging across all other factors. Specifically, this visualization tool shows the average response value for each...

Main Effect

In the design of experiments and analysis of variance, a main effect is the effect of an independent variable on a dependent variable averaged across the levels of any other independent variables. The term is frequently used in the context of factorial...

Levene’s Test

In statistics, Levene’s test is an inferential statistic used to assess the equality of variances for a variable calculated for two or more groups. It is a test for equal variances that can be used for data that is represented by a non-normal distribution. Some...

Level

Statistics level A statistics level is the value of input in an experimental run. The levels of independent variables (Factors). A level in factor analysis or an independent variable level is a way to break down the variables into smaller...

Lean Manufacturing

Lean manufacturing (also known as lean production, just-in-time manufacturing and just-in-time production, or JIT) is a production method aimed primarily at reducing times within the production system as well as response times from suppliers and to customers. It is...
