The data given is skewed towards one person who has visited twenty national parks. Therefore, using the mean would not give an accurate representation of the data. The mode is not a good choice either as there is no clear peak in the data. Therefore, the median would be the best choice as it is less affected by extreme values and gives a better representation of the typical visitor's experience.
