This is repeated until each student has ridden 10 waves. The brand of surfboard in this story is "the explanatory variable"

Step-by-step explanation:

the explanatory variable otherwise known as the the Independent variable.

in the scenario above the brand of surfboard is independent of the event because the brand doesn't matter in the experiment.
