Question

which statement correctly describes the data shown in the graph and the type of observation used?
o the ginkgo tree grew 14 feet; this is a qualitative observation.
o the bur oak trees growth rate averaged 2.5 feet per year, this is a quantitative observation.
o the bur oak tree is twice the height of the ash tree; this is a qualitative observation.
o the norway spruce grew more slowly than the sycamore every year; this is quantitative data.
tree growth after ten years
height (ft.)

Explanation:

Quantitative data involves numerical measurements like the height of trees in feet and growth rate in feet per year. Qualitative data is non - numerical, such as descriptions of how one tree grows slower than another. The gingko tree growing 14 feet and the bur oak's growth rate of 2.5 feet per year are numerical values, making them quantitative. Statements about one tree being twice the height or growing more slowly are qualitative.

Answer:

The gingko tree grew 14 feet; this is a quantitative 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 qualitative data.
