Calculating Average Values is easy with ACR TrendReader Software – the Compound Line function makes it simple to determine the running average or the arithmetic mean for a time interval.
Average values are often used when a signal is fluctuating such that it is hard to determine the overall picture of what is actually occurring. A running average takes into account large transgressions as it moves along the data set so every previous reading affects the latest value calculated on a weighted basis. The arithmetic mean is finite as it can be calculated on a fixed interval of data. Alternatively, the entire data set can be acted on using the sum divided by the size as given by Mean Average in the Statistics given for the graph in TrendReader.
