Correlation Analysis | Measure strength and direction of association between pairs of variables. |

Scatter Plot 3D | Visualise relationship between a response variable (Z) and two predictor variables (X and Y) |

### SPC Control Charts & Process Capability

SPC Tools | Application Hint |
---|---|

Xbar-S-Chart | When continuous data is collected in subgroups, with typical subgroup greater than 8 |

I-MR Chart | When continuous data is collected as individual samples (subgroups size = 1) |

P Chart | When proportion of defectives (or binomial events) are tracked |

NP Chart | When defectives (or binomial events) on a constant sample size are tracked |

U Chart | When defects per unit (or Poisson events per opportunity) are tracked |

C Chart | When defects (or Poisson events) on a constant opportunity are tracked |

Normal Process Capability | Determine how well a process output meets customer specifications, assuming normal distribution |

Capability Six Pack (Normal) | Statistical measure used to assess the performance and consistency of a process |

Machine Capability (Normal) | Assess and evaluate the performance and effectiveness of a machine or manufacturing process |

### Hypothesis Tests

Hypothesis Testing tools | Application Hint |
---|---|

One sample z-test | Determine whether the mean of a population differs significantly from a specified value, when the population standard deviation is known. |

One sample z test for summarized data | Determine whether the mean of a population differs significantly from a specified value, when the population standard deviation is known. |

One sample t test | Determine whether the mean of a population differs significantly from a specified value, when the population standard deviation is unknown. |

One sample t test for summarized data | Determine whether the mean of a population differs significantly from a specified value, when the population standard deviation is unknown. |

Two sample t test | Determine whether the mean of two samples differs significantly from each other. |

Two sample t test for summarized data | Determine whether the mean of two samples differs significantly from each other. |

Paired t test | Determine whether the mean of differences between two paired samples differs significantly from a hypothesized differences. |

One sample proportion test | Determine whether the population proportion differs from a specified hypothesized proportion. |

Two sample proportion test | Determine whether the population proportion of two groups differ. |

One Variance Test | Determine whether the variances of two or more groups or samples are significantly different from each other. |

Two variance test | Determine whether the variances of two independent samples are significantly different from each other. |

### Measurement System Analysis

MSA Tools | Application Hint |
---|---|

Type 1 GRR | Evaluate the effects of bias + repeatability from multiple measurements of one part. Typically done before a gage R&R study. |

Crossed GRR | Assess the variation in your measurement system when every operator measures every part in the study in a balanced design. |

Linearity & Bias | Assess the linear relationship and evaluate systematic errors |

Attribute Agreement | Assess agreement among raters in assigning attributes or categories to items. |

### Other Statistical Tools

Other Tools | Application Hint |
---|---|

Fit Regression Model | Model the relationship between categorical or continuous predictors and one response. |

AQL Sampling Plans | AQL based attribute sampling plans, as per ANSI/ASQ Z1.4 standard. |

One Way ANOVA | Compare the means of three or more groups to determine if there are statistically significant differences between them. |
