|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 Testing tools||Application Hint|

|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.|
