The College sends you a questionnaire whereby you must rank the 6 items with which you are most satisfied. The items are tuition cost, classroom size, course offerings by time, course offerings by topic, faculty, and textbook cost. In how many ways can you answer this questionnaire?
Homework Answers
Since we have to rank the 6 items, we will be giving a unique value and we will be arranging these ranks from 1 to 6. This therefore comes under the rule of permutations, where we are arranging n items all taken together, which is given by n!.
Therefore the number of ways we can rank the questionnaire is = 6! = 6 * 5 * 4 * 3 * 2 * 1 = 720 ways

This week's discussion is an application assignment. I want you to create your own survey. When conducting research, sometimes creating your survey instrument is the most tedious and time-consuming activity. For this week, let's keep things simple and say that you are conducting exploratory research on student perception/satisfaction of college textbooks--essentially, do students like their textbooks, dislike their textbooks, or not have an opinion about their textbooks. There are many questions to ask that may affect textbook perception/satisfaction. The genesis...
