Choose a performance analysis problem. List all system performance metrics and workload parameters. For each metric/parameter discuss the following:
a. Which index of central tendency would you use?
b. Which index of dispersion would you use?
Assume appropriate distributions, if necessary, and justify your assumptions. Include at least one example of each of the possible indices: mean, median, mode, geometric mean, range, variance, and percentiles. (This may require you to extend the problem or parameter list.)
