WebChemical, physical, and biological properties of water, sediment, and tissue samples from Montana. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and … WebA time series is a single set of data whose observations are ordered in time. The important difference with time series data is that the observations relate to a single quantity measured at a number of points in time. Therefore observations that are close in time are likely to be correlated and not independent.
