Statistics

Truncated Mean

This area allows to obtain a subset of results for Transactions with the extremes removed. This excludes non-representative values and provides values close to those obtained by the majority of end users.

• The percentage of results considered pertinent.
• Policy for selected result distribution.
  • Centered range (removes the same number of high and low values).
  • Remove only the highest values.

Truncated Mean is displayed in the Values tab of the Results section.

Percentiles

This area allows you to define three percentile values for Transactions.

Possible values for these fields are between 0.1 and 99.9 with a 0.1 granularity.

Raw data is approximated with a given relative approximation error of 0.001, i.e. 0.1% configurable in the rawdata.approximation.error property of the controller.properties file.

Percentiles are displayed in the Test Summary, Values and Graphs tabs of the Results section.

Time

This area allows you to specify the default time scale of the x-axis for the Runtime and Results graphs:

• Absolute is the option to display time in calendar dates.
• Relative displays the time elapsed from the beginning of a test. This is the default display mode.
