The following figure shows the last few lines of a Weighted Absolute report:
Relative Reports
Relative reports list the base response time as 1.00 and the other response times
relative to that base.
To define a Relative report:

, and then select the
Value relative to

and the
Individual sample data
options.
The final line of the report gives the geometric mean of the relative response times for
each report. To determine the geometric mean, TestManager multiplies the response
times and then takes a root of the product equal to the number of response times.
For example, if there are five response times, TestManager multiplies them together
and takes the fifth root of the product.
Mathematically, the geometric mean of a set of values
