Summary

This chapter presented several statistics that can be important for network management: mean, mode, median, range, standard deviation, and variance. Although the amount of work needed to analyze a single MIB variable may seem intimidating, please note that it is not necessary to analyze every variable that you have in your network baseline. Although the application of the correct statistic will assist you in the analysis of data and variables, it is more important to use the knowledge of your business operations to define critical applications and how their successful performance is measured. After you have accomplished this, you can use the statistical methods in this chapter to translate "how successful performance is measured" into what needs to be measured.
