Data collection, analysis, and graphing are essential in the workplace. Many industries, manufacturing in particular, now use statistical control processes to monitor their processes in order to ensure quality products. Often the front line employee is required to collect the data used for charting the manufacturing process; therefore, employees at all levels should be knowledgeable about and comfortable with using a variety of charts. As more and more quality teams, consisting of a variety of employees, are charged with the task of ensuring quality products, employees will need to have an understanding of probability and sampling.
