There is some research indicating that college students who use Facebook while studying tend to have lower grades than non-users (Kirschner & Karpinski, 2010). A representative study surveys students to determine the amount of Facebook use during the time they are studying or doing homework. Based on the amount of time spent on Facebook, students are classified into three groups and their grade point averages are recorded. The following data show the typical pattern of results. Non - User Rarely Use Regularly Use 3.7 3.51 3.02 3.45 3.42 2.84 2.98 3.81 3.42 3.94 3.15 3.1 3.82 3.64 2.74 3.68 3.2 3.22 3.9 2.95 2.58 4 3.55 3.07 3.75 3.92 3.31 3.88 3.45 2.8 Test at 0.05 level of significance to determine whether there are significant mean differences among three groups. Use 4 decimal places. STATISTICS = _____ COMPUTED VALUE = _____ TABULAR VALUE = _____ CONCLUSION = _____
