Weighted moving averages accomplish this. For example if the value for the
moving average is 100, and we want to add a new data point of 125, we can
calculate the new weighted moving average as 125x + 100(1-x), where x is
some number between 0 and 1. The sensitivity of the average to recent data
is determined by the value we choose for x.
