Flow weighted mean
Web– Flow Weighted Mean Concentration. TMDL – Total Maximum Daily Load. USGS – United States Geological Survey. Introduction : With a monitoring plan in hand, you may now be ready to head into the field to gather new data. This module will familiarize the reader with WebThe TP flow-weighted mean concentrations (FWMC) were among the highest of all basins (453 μg/L during the post-protection plan period) relative to other areas in this subwatershed. This basin had the largest contribution of TP load to the subwatershed during both the pre and post-protection plan periods.

The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others. The notion of weighted mean plays a role in … See more Basic example Given two school classes — one with 20 students, one with 30 students — and test grades in each class as follows: Morning class = {62, 67, 71, 74, 76, 77, 78, 79, 79, 80, 80, … See more Weighted sample variance Typically when a mean is calculated it is important to know the variance and standard deviation about that mean.
