Fundamentals of Hypothesis Testing
podcast episode with speaker Fred Schenkelberg
Let's make a comparison. Let's check our product's key characteristics against specifications, compare vendor life data, or compare the newest design changes to prior performance. We can and should do comparisons well using the appropriate statistical approach.
Let's examine a handful of parametric and non-parametric comparison tools, including various hypothesis tests. Plus how to best use these tools and when to set them aside and explore another approach.
Statistics is a part of what a reliability professional does; thus, we all should know the range, power, and applicability of the methods available. Let's explore how to make comparisons well.

SPC Sample Size Impact on SPC
In this webinar, we explore the impact that chart selection and sample size have on chart sensitivity (the ability to detect changes).

Understanding and Controlling Process Variation
Let's discuss process variation and how to measure, monitor, and control processes to minimize the differences from one part to the next.

10 Keys for Maximizing the Benefits of Your SPC Program
Progressive manufacturers use control charts to listen to their processes to detect and rectify potentially harmful changes.

What is Statistical Process Control or SPC?
You may have heard of Statistical Process Control, 6-sigma, Shewhart, the Japanese Economic Miracle, X̅ R Charts or perhaps none of them.

What is Process Capability Analysis (PCA)?
A process is considered capable' if it creates products that, with production natural variation, are still within what good' looks like.
