The Story: We are planning to conduct several studies looking at ways to improve the extent of undergraduate research participation. For each of the following, identify the appropriate statistical model to use for the combination of data and research hypothesis/question.

(a) We expect that students who take more credits per semester will give higher "intention to do undergraduate research ratings (using a 1-10 scale).

(b)Last semester we asked both juniors and seniors to choose between, (a) never done research, (b) had done research with graduate students but not faculty or (c) had done research with one or more faculty members.

(c)We think that sophomores will give higher "intention to do undergraduate research" ratings (using a 1-10 scale) than first year students, juniors or seniors. We have included this question (using a 1-10 rating for intention to do undergraduate research) on the annual student survey and have collected data each year from the 2001 entering class.

(d)When we survey the seniors, we expect to find that more women students will have done research in some faculty member's laboratory while more men students will have done research in some graduate student's laboratory.

(e)The two different lectures we want to compare to a control group are a "undergraduate research increases you chances to get into graduate school" and "doing research as an undergraduate helps you better understand how psychology works. Different sections of Psyc100 (How to be a Successful Psychology Student) will be in the different conditions. We want to know which condition result in the highest "intention to do undergradate research" ratings (using a 1-10 scale)

(g)All of our students take a methodology course while they are sophomores. We intend to ask them to rate their "intention to do undergraduate research" (using a 1-10 scale) three times during that semester: 1) the first day of class, 2) after a presentation on the benefits of research participation given during the 8th week, and 3) the last day of class.

(h)We asked both men and women students to tell us whether they have, (a) never done research, (b) had done research with graduate students but not faculty or (c) had done research with one or more faculty members. We think that most of those who choose "a" and "b" are men, whereas most of those who choose "c" will be women.

(i)Each year our graduate program admits several of our own undergraduate students. Using these folks in our study, we are able to compare their ratings of "the importance of undergraduate research participation" (using a 1-15 rating scale) when students are sophomores and when they are second year graduate students.
