Question

A forester surveys a sample of trees in a certain state forest and records the following information about each tree: species, height, diameter of trunk 4 feet above the ground, and type of leaves (needle or broadleaf). The quantitative variables he recorded are:

A) Species, height, diameter, leaves
B) Height, diameter, leaves
C) Diameter, leaves
D) Species, leaves

Answer 1

The forester recorded the following quantitative variables: species, height, diameter of trunk, and type of leaves. These variables involve numerical measurements and can provide objective data for further analysis.

Step-by-step explanation:

The quantitative variables recorded by the forester are: Species, height, diameter of trunk 4 feet above the ground, and type of leaves (A) Species, height, diameter, leaves). These variables are considered quantitative because they involve numerical measurements or counts. For example, height and diameter can be measured using units of length, and the number of trees of each species can be counted. These variables provide objective and measurable data that can be used for further analysis and study.
