12.15 - 13.30 Break
13.30 - 15.00 Workshop: Variability

17.30 End
  Content Day 2
09.00 - 10.00 Comparison of Data - Significance and Equivalence Tests
  • Analytical applications
  • Principles of statistical tests, significance tests (mean, nominal value, paired t-test, variance analysis)
  • Issues with significance tests, comparison of standard deviations (Fisher's F test)
  • Equivalence tests (mean, nominal value, paired) 
10.00 - 10.30 Break
10.30 - 11.00 Comparison of Data - Point Estimates
  • Simple comparison of means and precisions
  • Variability and differences between means
  • Probability of acceptance for the comparison approaches
11.00 - 11.45 Workshop: Comparison of Data
  • Statistical simulations
  • Comparison of comparisons: results for simple comparison, significance, and equivalence tests
11.45 - 12.30 Linear Regression
  • Analytical applications
  • Correlation analysis (coefficient of correlation and determination)
  • Unweighted linear regression, evaluation (residuals, sensitivities, intercept)
  • Requirements to calibration models
12.30 - 13.45 Break
13.45 - 15.00 Workshop: Linear Regression
  • Extrapolation and intercept, graphical evaluation of response functions
15.00 - 15.30 Break
