"Creswell's Research Design is an accessible and useful book that stimulates students through walk through experiences, use of exercises, and production of actual writing samples. It is a book that models the types of issues that best suit different approaches and allows students to understand when to use mixed methods. A cross-sectional study makes inferences about a population at one point of time. The purpose of these studies is not to follow up with the audience but to collect the data once. When the investigator repeats the cross-sectional study with later surveys he does not choose the same sample rather he takes another sample.
