Homework Help: Statistics

Posted by Samantha on Wednesday, September 9, 2009 at 10:07pm.

You want to compare the quality of several statistics textbooks.
(a) Identify two categorical variables and two quantitative variables that you would use to describe textbook quality. Give a reason for each of your choices.

So I think for the first categorical variable the materials like what is used to make the book and for the second the year it was published. Would those be considered categorical variables? I think I know the definition pretty well. And for the quantativ variable maybe the price? Or would that be categorical? And number of errors? Number of professors per college that use the textbook? Do any of those count as quantitative? Thank you for any helpful advice you might have!
