This graph shows how tall five types of trees were after they grew for 10 years. Which statement correctly describes the data shown in the graph and the type of observation used? The gingko tree grew 14 feet; this is a qualitative observation. The bur oak tree's growth rate averaged 2.5 feet per year; this is a quantitative observation. The bur oak tree is twice the height of the ash tree; this is a qualitative observation. The Norway spruce grew more slowly than the sycamore every year; this is quantitative data.

The correct option is,

The bur oak tree's growth rate averaged 2.5 feet per year; this is a quantitative observation

A quantitative observation is basically any piece of data that gives exact quantities, such as the exact growth rate per year in this case. Qualitative data serves to describe the subject, for example, the color change of an object may be described under qualitative observations
