Trimmed mean is a method of averaging, where a small designated percentage of the largest and smallest values is removed before calculating the mean. After specified observations has been removed, the trimmed mean is known by a standard arithmetic averaging formula. The estimation of the standard variance of such mean is obtained through an asymptotic linearization. The method is best used for data with large, erratic deviations or skewed distributions. It is expressed in percentage. Feel free to find the variance of trimmed mean using this online **trimmed mean calculator** with the known elements and percentage.
