<u>Answer:</u>
<em>Your instructor tells your class that you are all participating in a study on the effectiveness of note taking in class. The results show your class test scores improve significantly. Before concluding that your class takes effective notes, the research should be aware </em><u><em>of the Interaction and group discussion.</em></u>
<u>Explanation:</u>
It has been found that the <em>performance of the students</em> tends to increase when they are actively interacting in the class with instructor and colleagues. Interaction is the two-way process of communication where opinions about a common topic are shared between the involved parties.
Interaction helps in memorizing the facts and building a clear concept of the fact. These certainly tends to improve <em>the result of students </em>in tests and help attain better grade.
<h3>content validity - how well a test measures the behavior for which it is intended</h3>
Example -
<em>A mathematics teacher develops an end-of-semester algebra test for her class. The test should cover every form of algebra that was taught in the class. If some types of algebra are left out, then the results may not be an accurate indication of students’ understanding of the subject. Similarly, if she includes questions that are not related to algebra, the results are no longer a valid measure of algebra knowledge.</em>
Another example is that content validity can be used in a clinical or business setting

During the colonial era, the region of Chesapeake was filled with many diseases that infected a lot of its people. Since our medical knowledge hasn't developed much back then, a lot of the cases were resulting in death.</span>
Cos(pi/2 - x) = sin(x). sec(x) = 1/cos(x), so the left side would be sinx/cosx = tanx. So it checks out.
