Answer #1

There is a strong positive linear relationship or correlation exists between the two variables time spent revising and exam performance for students. In most of the studies, it was observed that if the time of revising increases, the performance of the student in exam also increases. A strong positive association was revealed between these two variables. There is a strong positive association between the study hours and exam performance by the students.

A professor comes up with an exam to measure learning in students. The exam is given two separate times in six different classes. The professor finds that for ALL classes students showed a consistent (similar magnitude) improvement in performance from time 1 to time 2. When comparing the performance of each class at time 1 the professor found that the results were not consistent (large variability in scores). True or False: In the above scenario the exam most likely had...
