A group of college students identified to one of four types of music: rock and roll, jazz, country, and showtunes. Ten students were selected for each group. In addition to this the psychologist wondered if gender would have an impact on the hours studying as well so each of the 4 groups were separated into 10 male and 10 female (80 students total), and each of these student's hours studying were then recorded for a one-week period. The data is shown in the following table. female female female female female female female female female female male male male male male male male male male male Rock & Roll 2 3 2 5 2 6 4 5 3 4 3 3 3 5 6 4 m 3 4 5 4 ++ Jazz 6 5 6 7 6 5 5 6 7 4 6 4 3 3 4 5 4 5 4 3 Country 8 8 6 7 6 7 8 5 6 7 9 8 4 5 3 2 Ist 4 6 8 5 Showtunes 8 8 8 7 6 5 6 7 7 9 5 4 5 4 3 4 5 2 6 7
