Question

Quizplus · Accepted Answer

The number of blooms is a scale dependent variable because it is a quantitative measurement. Additionally, because there are two distinct groups being compared (talking versus not talking to the plants), a parametric test would be appropriate to analyze the data. Therefore, the best choice is D, scale dependent variable and parametric test.
