I held a Webinar for Pyzdek Institute students entitled Statistical Surprises and Absurdities. Topics discussed included sampling bias, misused and misleading averages, distorting results by use of selective data weighting, selective reporting, missing information, distorted graphics, Say What? and So What? statistics, and much more! Here’s the recording
Here’s a link to the slides presented in the webinar.
An overview of Six Sigma taken from one of the lessons in Pyzdek Institute Six Sigma Black Belt training.
Here’s an exercise from Pyzdek Institute Green Belt training. At a pharmaceutical company they have developed an IV drip device that has an advertised drip rate of 5 drops per minute. A sample of 10 “drippers” is taken from the process and tested by counting the number of drips that occur during a 10 minute span. The average for each dripper is found by dividing the total drops by 10. The results are (average drops per minute):
Use the t test to conduct a test of hypothesis and answer this question at a 95% confidence level: “Is the process producing IV drip devices that average 5 drops per minute?” Also use confidence intervals to answer the same question.
This video shows a way to answer these questions using the QI Macros software.
