  • here is a book I own where you can brush up on your statistical working knowledge. You will need it for performance testing, https://www.amazon.com/Statistics-Dummies-Lifestyle-Deborah-Rumsey/dp/1119293529 – James Pulley Aug 02 '17 at 21:39

The 90th percentile is the value for which 90% of the data points are smaller

The 90th percentile is a measure of statistical distribution, not unlike the median. The median is the middle value. The median is the value for which 50% of the values were bigger, and 50% smaller. The 90th percentile tells you the value for which 90% of the data points are smaller and 10% are bigger.

Statistically, to calculate the 90th percentile value: 1. Sort the transaction instances by their value. 2. Remove the top 10% instances. 3. The highest value left is the 90th percentile.

Example: There are ten instances of transaction "t1" with the values 1,3,2,4,5,20,7,8,9,6 (in sec). 1. Sort by value — 1,2,3,4,5,6,7,8,9,20. 2. Remove top 10 % — remove the value "20." 3. The highest value left is the 90th percentile — 9 is the 90th percentile value.

The 90th percentile value answers the question, "What percentage of my transactions have a response time less than or equal to the 90th percentile value?" Given the above information, here is how LoadRunner calculates the 90th percentile.enter link description here
