Gage R&R Test (MSA) | A statistical tool that analyzes the repeatability and reproducibility of continuous (a.k.a. variable or numerical) values for a Measure System Analysis (MSA). The two types studies use that depend on the parts used in the MSA: 1) Crossed - used when the same parts are used by each operator for each trial, and 2) Nested - used when different parts are used by each operator for each trial. |

General Linear Model (GLM) | A statistical tool that evaluates the relationship or correlation between a primary continuous (a.k.a. variable or numerical) value with multiple continuous or discrete (a.k.a. attribute or categorical) values. |

Goodness-Of-Fit Test | One of the Chi-Square tests that is used for comparing an observed discrete (a.k.a. attribute or categorical) value with that value's fixed or evenly proportionate set of outcomes. For example, a coin has only two types of outcomes so the expected outcome should be 50:50, or a die has six sides so its expected outcome for each side is 1/6. |

Graphical Summary | A chart in Minitab that displays a summary of the statistical characteristics for a given continuous (a.k.a. variable or numerical) value. The display includes a histogram, boxplot, and a display of the confidence intervals. It also includes statistical details like the mean, median, variance, skewness, etc. and the results from a normality test. |

Green Belt (GB) | A role in Six Sigma by someone who has a moderate expertise in the Six Sigma (and possibly Lean) tools and concepts. The actual functions and responsibilities for this role vary but in general this person has a part-time dedication to leading projects that may yield benefits that are considered small for the organization. Their projects generally cover a shorter timeframe (like 1 to 3 months) and usually have a scope that is more limited to their functional area. This is a role that is commonly certified by many training organizations, although the requirements for those certifications vary considerably. This role is considered to be just below a Six Sigma Black Belt (BB) role, but isn't necessarily a requirement before attaining a BB certification. |
