D) the barometric method.

Question

Quizplus · Accepted Answer

Exponential smoothing with a small weight value (also known as a low alpha value) places more emphasis on older data, leading to a greater smoothing effect compared to using a moving average based on a small number of periods, which would be more responsive to recent changes. The root-mean-square error and the barometric method are not directly related to the smoothing of data series.
