Question

which statement correctly describes the data shown in the graph and the type of observation used? the ginkgo tree grew 14 feet, this is a qualitative observation. the bur oak trees 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. tree growth after ten years height (ft.) ginkgo sycamore norway spruce green ash bur oak

Explanation:

Quantitative observations involve numbers (like growth rate in feet per year, height in feet). Qualitative observations are non - numerical (like one tree growing more slowly than another). The gingko tree growing 14 feet is a numerical value, so it's quantitative. The bur oak tree's growth rate of 2.5 feet per year is also numerical and thus quantitative. Saying the bur oak tree is twice the height of the ash tree is a comparison using a numerical relationship, which is quantitative. Saying the Norway spruce grew more slowly than the sycamore is a non - numerical comparison, which is 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.
