Data Interpretation and Implication
Simpson's Paradox
• a common but misleading statistical phenomenon rooted in the differing sizes of subgroups. Put simply, Simpson's
Paradox reveals that aggregated data can appear to reverse important trends in the numbers being combined.
Example
• Which airline would you travel on?
• 4 airports, 2 airlines with delays

Business Data Challenges
• Revenue depends on applications
• Productivity of employees depends on applications
• End users expectations of technology continue to rise
• Cost cutting can put business service performance at risk
28% of users will not
return to a website if it’s
not performing well.
A one second delay in response time
of web applications can impact
customer satisfaction by up to 16%.
Issues with application performance are impacting
overall corporate revenue up to 9%

Technical Data Challenges
• Most problems are still discovered by end users
• Problem resolution takes too many people too long
• Multiple tools give different answers
• Problem reproduction in QA delays resolution
•Too many end users to predict behavior with the app
• Rate of application change overloads traditional support
Through 2012, 80% of application performance and availability
problems will be blamed on the network, but the
network will only represent 20% of the root cause.
