Knowledge of some moderns methods of mathematical statistics oriented to soft product (Statgraphics and Matlab).
1. Normal distribution:
Confidence limits and test hypotheses for mean, variance,
difference of means and ratio of variances.
Comparing two sample of equal size.
2. Parametric and non-parametric tests.

4. Multiple linear regression:
Estimation of coefficients. Method of least squares. Variances and
covariances of the regression coefficients. Examination of
residuals. Standard errors of predicted values. Analysis of
variance. Confidence intervals and tests of hypotheses.
