How JASP is Used in our Training

We use JASP tutorials to teach both descriptive and inferential statistics within our Lean Six Sigma training programs. These tutorials help participants understand the statistical foundations of process improvement. Our current and planned training offerings include:

  • Descriptive statistics (Histogram, Pareto)
  • Inferential statistics (Probability Plots, Empirical CDF, ANOVA, Regression, Chi-square)
  • Statistical Process Control and Process Capability Studies
  • Measurement Systems Analysis (Attributes Agreement and Gauge R&R)
  • Design of Experiments (Factorial and Respons Surface)
  • Predictive Analytics (Classification and Regression Trees)
