a. Why researchers are interested in describing measures of the center and measures of variation of a data set? Discuss

b. The average of data set is influenced by extreme values while the median is not. In other words, the median is not resistant to outliers but the average is not. True or False. Discuss and offer examples.

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.
