Getting Rid of the Jitters: Finding the Trend
Is there a trend toward global warming, or is the relatively warm weather of recent years just part of the variability expected in a process like the weather? This question is much debated partly because it is difficult to see long-term trends in data that is subject to many short-term fluctuations (sometimes called “jitters”). Some of the fluctuations can be removed, however, by “smoothing” the data. In this lesson, moving averages will be used to smooth temperature data from the coastal northeastern United States so that trends can be spotted more easily.
