You explain to your study group that a hypothesis is:
I I I I I I I I I




an explanation thataccounts for careful observations.
I I I I I




a proposition thatwill be true and fits the known facts.

Based on the literature, you hypothesize that students in traditional biology lectures will have the
I I I I I I I I I I I I I I




same grades as students in online biology lectures. You decide to test your hypothesis by
I I I I I I I I I I I I I I I




comparing grades of students in traditional and online biology lectures over a semester. As a result
I I I I I I I I I I I I I I I I




of the experiment, you observe that the grades in the traditional lectures and the grades in the online
I I I I I I I I I I I I I I I I I I




lectures are not significantly different. What do these observations allow you to do?
