Hailey is running a research project that examines whether students who use electronic versions of textbooks perform as well as students who use traditional paper copy textbooks. She predicts that students who have
paper copy textbooks will perform better than students with e-books. She gets permission to divide a PSY 205
section in to "e-book" and "paper book" groups. At the end of the semester, she collects the students' final
grades and determines that the groups are not significantly different from each other (they did equally well in the
class). Which of the following statements is/are TRUE of Hailey'sresearch?
O Her study is a correlation.
O She has 2 independent variables: e-book and paper copy book.
O Her independent variable has 2 levels.
O Her hypothesis is nonfalsifiable and untestable and is therefore not scientific.
