discussion 4167

The coefficient of variation and the standard deviation are two measures of variability or dispersion among data values. Provide two different sets of ten data points each as examples. Calculate the standard deviation and coefficient of variation for each data set, being sure to attach your Excel file to show your work. Explain which of the two mentioned measures can more accurately specify which of these two data sets has more variability or dispersion in their data values and why.

Research the method behind the Excel function “QUARTILE.EXC” for calculating quartiles for a given data set. Summarize this method in your own words and discuss how it differs from the method presented in the textbook and lecture.
