Question

A study was done to determine if the method of instruction (either lecture or discussion) depended on the type of class which was being taught. Twenty art classes, seventeen math classes and twenty-five science classes were observed. The method of instruction, discussion or lecture, was recorded. Which of the following best describes the relationship between method of teaching and type of class? There appears to be no relationship since the number of discussion class and the number of lecture classes was exactly the same. No association can be determined since the number of art, math and science classes were not exactly the same. There appears to be an association since the art class was less likely to use discussion then either math or science. There appears to be an association since the number of math and science classes is greater than the number of arts classes. A measure of association cannot be determined from these data.

Explanation / Answer

D) is the correct answer. There appear to be an association since the number of math andscience classes is greater than the number of arts classes.
