Final answer:
The smoothing adjustment (alpha) is always set to 0.5 is True.
Step-by-step explanation:
The statement is True. The smoothing adjustment, also known as alpha, is indeed set to 0.5 in the context of exponential smoothing methods. Exponential smoothing is a time series forecasting technique used to predict future values based on historical data. It places more weight on recent data points and less weight on older data points, allowing for a smooth and accurate forecast.
