Statistics and Statistical Process Control in Manufacturing

Learn about the primary objective of statistics which is to measure and characterize variability, and how statistical process control is used to control variability in manufacturing processes. Explore an example of a supplier filling soda cans marked as 12 ounces, where variability in the process results in some cans containing more or less soda than the specified amount.
