Question

an experiment was performed on seeds. researchers exposed seeds to different levels of radiation (low, medium, and high).

plant height was then measured to learn how plant height was impacted by radiation level.

in this experiment, ‘plant height’ represents the…

a. independent variable; graph this on the x axis
b. independent variable; graph this on the y axis
c. dependent variable; graph this on the y axis
d. dependent variable; graph this on the x axis

Answer 1

In this experiment, 'plant height' is the outcome that is being measured to see how it is affected by the different levels of radiation. This means that 'plant height' is the dependent variable.

Therefore, the correct answer is:

**c. dependent variable; graph this on the y axis**
