Workshop: Biostatistics for Beginners

Tuesday, October 15, 2019 | 9:30 am – 5:30 pm


Nancy Sajjadi, MSc, Independent Quality Consultant


Biostatistics is the science of learning from biological data. Inferential statistics use data from a sample to make generalizations or predictions about a population. The process of sampling naturally incurs error and statistics are needed to measure, control, and communicate the uncertainty of reported results. This workshop is intended for people who generate or review bioassay data, but have minimal training in statistics. This slower-paced course will help participants understand the meaning of commonly encountered statistical information and expand their knowledge of fundamental concepts and tools that are applicable to their daily work.


  • The Role of Statistics in Development of Biologics and Lot Release Specifications
  • Assays, Measurements, Averaging and the Meaning of Uncertainty
  • Accuracy vs. Precision
  • Populations vs. Samples
  • Parameters vs. Statistics
  • The Normal Distribution
  • Inferential Statistics and Sampling Error
  • Standard Error of the Mean
  • t values and p values
  • Confidence Intervals
  • Difference vs. Equivalence Testing
  • Type I and Type II Errors and Statistical Power
  • Dose Response Curve Models
  • The meaning of r2
  • Log transformation
  • Interpreting Assay Validation Guidance
  • USP Metrics for Evaluating Assay Precision

The commitment to participants:  Each participant is likely to arrive at the course with the expectation of examples or explanations to address issues that are specific to them or their organization. To ensure that participants are satisfied, the instructor is open to receiving non-confidential questions in advance for consideration in customizing the course material. The instructor will assess each question to ensure it matches the scope of the workshop. If you have question(s) the instructor should address at the workshop, email it to Kaitlyn Barago, Workshop Organizer.
