Index of Central Tendency
• What Index of Central Tendency should be used to report?– Response time (symmetrical pdf)– Number of packets per day (symmetrical pdf)– Number of packets per second (skewed pdf)– Frequency of keywords in a language
• How would you summarize an average PC configuration?– CPU type– Memory size– Disk size– Number of peripherals
(Jain, 12.8 and 12.9)

Indices of Central Tendency and Dispersion
•CPU times (in ms) for 11 workloads0.74, 0.43, 0.24, 2.24, 262.08, 8960,
4720, 19740, 7360, 22440, 28560– What index of central tendency to use?– What index of dispersion to use?
•Disk I/O’s22, 33, 14, 15, 42, 28, 33, 45, 23, 34, 39,
21, 36, 23, 34, 36, 25, 9, 11, 19, 35, 26, 16, 23, 34, 24, 38, 15, 13, 35, 28
– What index of central tendency to use?– What index of dispersion to use?
