Week 3, DQ 5

Use the University of Phoenix Library and select a research article from a peer-reviewed journal that includes a chart to discuss the make up of the sample used. This may be a frequency chart, histogram, pie chart etc. Explain why this is a good (or bad) use of the type of chart and how additional charts may be used. (be sure to reference the article)

Also, how do you use charts in your career today? Which type and how does this assist with interpretation of data?

The article I selected deals with control charts comparisons. It shows monitoring of variability using exponentially weight by moving samples.
