percentileaveraged

percentileaveraged is a statistical concept that refers to the average of specific percentiles of a dataset. Instead of calculating a simple mean or median, percentileaveraged involves selecting one or more percentiles (e.g., the 10th percentile, the 90th percentile) and then computing the arithmetic mean of these chosen values. This method is often employed to mitigate the impact of extreme outliers in a dataset, as it focuses on the central portions of the distribution rather than the absolute highest or lowest values. For example, trimming the top and bottom 10% of data and then averaging the remaining 80% is a common application of this concept, sometimes referred to as a trimmed mean orWinsorized mean, depending on the exact methodology. The choice of which percentiles to average is dependent on the specific goals of the analysis and the characteristics of the data. It provides a measure of central tendency that can be more robust to anomalies than a simple average.
