Webinar on Normality Tests and Normality Transformations: Explanations, Justifications, and Uses

B2B 1

EVENT DESCRIPTION

Overview: 

Normality Tests and normality transformations are a combination of graphical and numerical methods that have been in use for many decades. These methods are essential to apply whenever a statistical test or method is used whose fundamental assumption is that the inputted data is normally distributed.

Normality "testing" involves creating a "normal probability plot" and calculating simple statistics for comparison to critical values in published tables. A normality "transformation" involves making simple changes to each of the raw-data values, such that the resulting values are more normally distributed than the original raw data. 

Evaluation of the results of "tests" and "transformations" involves some objective and some subjective decisions; this webinar provides guidance on both types of decision making. 

Why should you Attend: 

The calculations used in many statistical tests and methods require that the inputted data be "normally distributed". Such calculations include those for Student's t-Tests, ANOVA tables, F-tests, Normal Tolerance limits, and Process Capability Indices. Unless the raw data used in such calculations is "normally distributed", the resulting conclusions may be incorrect. Therefore, being able to assess whether or not data is "normally distributed" is critical to ensuring that a company's "valid statistical techniques" are "suitable for their intended use" (as required by the FDA).

Dimensional data (length, width, height) are typically normally distributed. But many other types of data sets are almost always non-normal, such as: tensile strength, burst pressure, and time or cycles to failure. Some non-normal data can be transformed into normality, in order to then allow statistical calculations to be valid when run on the transformed data. 

This webinar explains what it means to be "normally distributed", how to assess normality, how to test for normality, and how to transform non-normal data into normal data, and how to justify the transformations to internal and external quality system auditors.

Speaker Profile:

John N. Zorich has spent 35 years in the medical device manufacturing industry; the first 20 years were as a "regular" employee in the areas of R&D, Manufacturing, QA/QC, and Regulatory; the last 15 years were as consultant in the areas of QA/QC and Statistics. His consulting clients in the area of statistics have included numerous start-ups as well as large corporations such as Boston Scientific, Novellus, and Siemens Medical.
