Based on the literature, you hypothesize that students in traditional biology lectures will have the same grades as students in
online biology lectures. You decide to test your hypothesis by comparing grades of students in traditional and online biology lectures over a semester. As a result of the experiment, you observe that the grades in the traditional lectures and the grades in the online lectures are not significantly different. What do these observations allow you to do
<em>The observation allows one to make a conclusion based on the hypothesis.</em>
From the observation that the grades in the traditional lectures are significantly different from the grades in the online lectures, the hypothesis that students in traditional biology lectures will have the same grades as students in online biology lectures would be rejected.
The observation of the significant difference, thus, helps to reject the initial hypothesis, also known as the null hypothesis.
Humans can cause an imbalance in the food system. For example if we over hunt, we may cause a keystone species to go extinct which would ruin an entire ecosystem.
