Question

4. Martin has hypothesized that the size and types of trees differ between valleys and higher elevations. He sets up a transect line in a wooded valley and randomly creates three 10 x 10 meter plots along the transect line, recording GPS coordinates for the northwest corner of each plot. He identifies and measures (diameter at breast height) every tree within the plots. He repeats this procedure in a wooded area on the ridge above the valley.

Are Martin’s methods for identifying and measuring trees quantitative, qualitative, or semi-quantitative?

Explanation / Answer

This is a semi qualitative assessment. The motive of this experiment is to compare the sizes and types between two elevations. Once measured, the values are compared with the two different locations like higher or lower.
