The moving average method can also be referred to as a(n) _____ method. When k is even, the window is centered about the current and previous elements. A moving average can be used to provide support in an uptrend, the average can act as a base ground or 'support'. The smoothing effect of the moving average model provides for a “cleaner” For example, using the 100- and 200-day moving averages, if the 100-day moving average crosses below the 200-day average, it's called the death cross. Weighted moving averages are typically employed to "smooth" chronological data while attaching a greater level of significance to the terms that are deemed to be the most important. MAD=0.
