The Outliers are not displaying in some AAI reports

Issue/Introduction

Some of the dots in the AAI reports are showing as outliers. For example:

 

Environment

Product: Automation Analytics & Intelligence v6.5.x

Cause

By design

Resolution

The AAI follows the 4 Standard deviation rule. For example below:

 

After calculating mean and duration of the data above, the points/dots above 40 are still falling under 4 Standard Deviations and that is the reason they are not shown as outliers. For the above data, the following mean and standard deviation values are as follows:

So, the 4 Standard Deviations will be Mean + 4 SD =( 15.44 + (4 X 8.47))=15.44 + 33.88= 48.88

Therefore, any points below 49 will not be considered as outliers.
