Comparing Moving Average Time Spans
An analyst is examining a 100-year dataset of annual global temperatures, which exhibits considerable year-to-year fluctuations. They create two separate charts to visualize the long-term trend: one using a 5-year moving average and another using a 50-year moving average. Compare these two approaches. What is the primary advantage of using the 50-year moving average over the 5-year moving average, and what is its main disadvantage in this context?
