How Often Should You Take Measurements for Control Charts?

Six Sigma Formulas Cause Math Phobias

In the book, The Case Against Education: why the Education System is a Waste of Time and Money, author Bryan Caplan argues that, beyond reading, writing and basic ‘rithmatic, “most of what people learn in high school and college is unnecessary and quickly forgotten.”

jcaqo falls rates data

The first year, 2003, had only 200 falls because they started measuring in July. The first full year of measurement was 2004.

It would be easy to turn these into control charts, but the authors chose a boxplot with a trend line of predicted falls.
