Statistical calculations and tools are applied extensively in pharmaceutical analysis including
  • ƒProcedure development and validationƒ
  • Transfer of analytical procedures
  • Setting or verification of specification limits
  • Data evaluation, comparison and trending
The ICH Q10 Guideline “Pharmaceutical Quality System”, the FDA Guidances on Process Validation and Methods Validation require monitoring of “process performance and product quality” and “Trend analysis on method performance” throughout the product lifecycle. Hence the appropriate use of statistical trending and evaluation tools has become mandatory.

Consequently, a thorough understanding of statistical fundamentals is essential in order to be able to select parameters and test methods that are ‘fit for purpose’.

Do you speak statistics?
In addition, such an understanding facilitates the communication with other technical and regulatory functions applying statistical tools in order to ensure an overall consistent approach.


The Live Online Training will provide the participants with recommendations, tools and examples to apply scientifically and pragmatically sound statistical principles to their day-to-day business as well as to meet future challenges described above.

The relevance of such statistical tools is also increasingly recognised by the Compendia, as reflected, for example, in the USP General Information Chapter <1010> “Interpretation and Treatment of analytical data” and the recently introduced <1033> “Biological assay validation” together with the proposed General Chapter <1220> on Analytical Procedure Lifecycle.
Statistical tools are needed, for example, to evaluate:
  • Distribution of data and its parameters
  • How to detect outliers and trends?
  • How to establish the total variability of the method?
  • How to identify method parameters that must be controlled?
  • Method performance and specification Limits
    - Which accuracy and precision is needed to achieve an acceptable risk of OOS results?
    - Scientifically based justification and optimisation of the reportable result (single or average?)
    - What are the requirements for impurity methods?
  • Comparison of methods and data
  • What are the requirements for calibration models?
  • How to optimise the number of calibration replicates on a scientific basis?
A brief discussion of supporting software tools (e.g. Excel, Minitab, JMP) to facilitate the generation of statistical information in a consistent manner will be undertaken.

One of the main features of this Live Online Training is the Balance of presentations and more than five hours of practical exercise workshops which will allow participants to gain ‘Hands on’ practical experience in applying the statistical methods described. By means of statistical simulation tools, the participants will gain intuitive understanding of the consequences of appropriate and inappropriate performance parameters, for example the relationship between precision and OOS results.

Target Group

This best practice oriented course is designed for analytical laboratory managers and their colleagues charged with the day to day management and evaluation of laboratory data throughout the lifecycle, i.e. in method development, validation, transfer, specification setting, batch release and stability, continuous performance verification and change control.
QA, manufacturing and regulatory affairs professionals will benefit from participation by gaining a clear understanding of the statistical fundamentals which are important to implement scientifically sound and pragmatic tools to conform to GMP and regulatory requirements for example Product Quality Review.

Technical Requirements

For our webinars, we use Cisco WebEx, one of the leading suppliers of online meetings. At you can check if your system meets the necessary requirements for the participation at a WebEx meeting and at the same time install the necessary plug-in. Please just enter your name and email address for the test. If the installation is not possible because of your rights for the computer system, please contact your IT department. WebEx is a standard nowadays and the necessary installation is fast and easy.

*** Optimised as Online Event – Interaction ensured***
Q&A sessions ensure interaction and that all questions are answered.
During the workshops, the participants will be invited to switch on their microphone to join the discussion.
If you want to take part in it, please make sure that you have a headset or that your computer has a built-in microphone.
In addition, you will have the opportunity to ask questions per chat, which the speakers will then answer. Furthermore, the speakers will work with live poll questionnaires for gathering feedback and asking questions.
Please note: The chat and poll questionnaires are anonymous. The names of the people discussing during the workshops will be visible for all participants. The Live Online Training will not be recorded.
