WAPT and Standard Deviation

Recommended Posts

Guest zooser

Hi,

 

I was wondering if WAPT calculates standard deviation for the data set that it records?

 

If WAPT itself doesn't calculate this, can it be calculated from the data set that WAPT does provide?

 

TIA

Hi, it is used for calculating Avg90. Avg90 is a so called 90 percentile, in case of WAPT it is the evaluation of time frames in which 90% of virtual users are kept within. The approximate formula for its calculation is Percentile90=Avg+1.275*StandardDeviation.

 

You can find more info on Avg90 here, in the forum.
