In jmeter 3.0 I have created dashboard report but getting problem in reading some matrices like 90th, 95th and 99th pct in statistics. What these actually means?

The 90th percentile is around 2.75 seconds (90% is processed within 2.75 seconds) The 95th percentile tops out at about 3.25 seconds (95% is processed within 3.25 seconds) The average response time is around 2.0 seconds (blue line).
A percentile is the value at a particular rank. For example, if your score on a test is on the 95th percentile, a common interpretation is that only 5% of the scores were higher than yours.
n. the location of a score in a distribution expressed as the percentage of cases in the data set with scores equal to or below the score in question. Thus, if a score is said to be in the 90th percentile, this means that 90% of the scores in the distribution are equal to or lower than that score.
A BMI measurement at or over the 95th percentile line on the chart puts someone in the obese range.
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
