The boxplots show an overall increasing trend in gas prices over the 3-year period, as the median price increases from year to year. The spread of prices is also increasing, as seen by the widening of the boxes and whiskers. The distribution is skewed to the right, as the upper whiskers are longer than the lower ones. Additionally, there are three high outliers in 2005, indicating some extreme prices in that year.
