InnoVenton and The Downstream Chemicals Technology Station

Statistical techniques are used to reach objective conclusions in process control.


Who should attend?

Process operators, engineers and persons responsible for maintaining and extending quality control.

Why you should attend

It is essential to use statistical techniques to be able to quantify process variability. Spreadsheet programs such as Excel make these techniques accessible for the non-mathematician. It is therefore no longer necessary to purchase expensive and user-unfriendly statistical packages to do statistical analysis as most statistical tests and calculations can now easily be performed by using widely available spreadsheets.

Prior learning requirements

A relevant three year graduate or diploma qualification. Participants need to have a good working knowledge of Excel. No previous knowledge of inferential statistics is required.

Course objectives and structure

After completion of this course, the participant will be able to:

  • Obtain descriptive statistics from a set of continuous and categorical data;
  • Define and interpret the concepts of accuracy, precision, random errors and systematic errors;
  • Obtain and interpret confidence intervals for averages and proportions;
  • Perform tests of significance, such as the t-Tests, ANOVA, and interpret their associated p-values;
  • Perform a bivariate regression analysis and validate the resulting model;
  • Create and interpret R-charts, S-charts and X-charts based on production data;
  • Perform a process capability study.

The course emphasis is on the interpretation of statistical results rather than on the calculation thereof.

Each participant will use her / his personal laptop, which should have the software MS Excel downloaded on it, and will analyse real and relevant data sets under the guidance of the lecturer. We recommend that the participant brings a memory stick so that he / she can download course material for later reference.

The students are evaluated by completing a test on the work covered.
