PPavg

PPavg is an acronym used across several technical domains to denote an averaged quantity, but there is no universally accepted definition. Its exact meaning is context-dependent and must be inferred from the source in which it appears.

In statistics and data analysis, PPavg is sometimes used as shorthand for probability-weighted average, a mean that assigns probabilities to data points and uses those probabilities as weights. In signal processing and metrology, PPavg may refer to an average derived from peak values—such as the average of instantaneous peaks over a time window—or to an average power metric computed from instantaneous power samples. In performance assessment, PPavg might stand for a domain-specific percentile-averaged metric or other context-specific averages; definitions vary by author or standard.

Interpreting PPavg requires examining the accompanying definitions, units, and the window or samples over which the average is taken. If a PPavg is defined over a time interval, the interval length, sampling rate, and whether the result is arithmetic, geometric, or weighted should be specified. When comparing results from different sources, ensure alignment of the exact PPavg meaning and methodology.
