The article offers insights on how to determine the capability of power tools by using data about the fastening process. Among the factors that influence the fastening process are variation in air pressure, friction, part dimensions and operator skill. It notes that statistical analysis can inform engineers when a certain variation is not acceptable. It cites that one method to look at fastening data is with a histogram, a bar graph that determines how often certain values happen.
