What Do These Results Mean?

A recent study compared 2 groups of students who registered for a history course. One group studied history in a conventional face-to-face classroom. The other group studied an online Internet course, and studied only at home. Students who did the online course at home got higher test scores than students who studied in the classroom. The researchers did statistical analyses to see if there were statistically significant differences between scores in the two groups of students. These analyses showed that students in the online course got significantly higher test scores than students in the face-to-face classroom course.
