WebApr 1, 2024 · Flow-weighted mean concentrations analysis. Flow-weighted mean concentrations (FWMC) (mg L-1) were used to quantify the concentration proportional to a corresponding flow volume. The FWMC for each parameter were derived from the concentrations, sample time window, and flow volume for each sample. 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.
