Any examples with solutions similar to this would be helpful: "For the given research objective, explain which experimental design you would choose and write it down in scientific notation."
You may refer to the test banks of the Marketing textbook which are available for faculty members. Many publishers, such as Pearson, have etexts online for teacher education.
I also recommend you Pearson's system. If you use the books of Pearson you will get access to virtual MyLab - where you will find teacher's guide, cases, presentations of the topics, video's and tests as well.
