A study of 483 first- year college women suggests a link between media usage such as texting, chatting on cell phones, and posting status updates on Facebook, and grade point average. Students reporting a higher use of media had lower grade point aver-ages than students reporting a lower use of media.
a. Does the study suggest that use of media and grade point aver-age are positively correlated or negatively correlated?
b. Do you think that there might be a cause- and- effect relation-ship between use of media and grade point average? Explain.
