From PPM version 9.7, you can statistically evaluate data in Data analytics and display the corresponding standard deviation and percentiles, such as median, in the analysis.
Standard deviation is available by default for measures with the DOUBLE, TIMESPAN, and FACTORYTIMESPAN data types. Data type LONG is not supported, the option is disabled. If you want to deactivate standard deviation for a measure, set the standarddeviation (TRUE|FALSE) attribute in the criterion-definitions configuration element to FALSE.
Percentiles can be calculated and displayed in PPM for all measures.
