The paper “ The Effect of Multitasking on the Grade Performance of Business Students” ( Research in Higher Education Journal [ 2010]: 1– 10) describes an experiment in which 62 undergraduate business students were randomly assigned to one of two experimental groups. Students in one group were asked to listen to a lecture but were told that they were permitted to use cell phones to send text messages during the lecture. Students in the second group listened to the same lecture but were not permitted to send text messages during the lecture. Afterwards, students in both groups took a quiz on material covered in the lecture. The researchers reported that the mean quiz score for stu-dents in the texting group was significantly lower than the mean quiz score for students in the no- texting group. In the context of this experiment, explain what it means to say that the texting group mean was significantly lower than the no- text group mean.
