Histograms, Dotplots, Boxplots

Histograms allow you to clump data by an interval instead of individual data. For example you could sort the tree heights into intervals of 5 and see the bigger picture. What you lose is the individual data of each tree's height.

Dotplots allow you to see all of the individual data. This is good if there are not a lot of data (dots), or if the range of data are small.

Boxplots show the range of data on a number line. It shows how the data is split into 4 quartiles. It also shows the box where the middle 50% of the data is.
