At West View High School, every freshman (Fr) and sophomore (So) has either math (M), science (S), English (E), or history (H) as the first class of the day. The two-way table shows the distribution of students by first class and grade level.

A 6-column table has 3 rows. The first column has entries Freshman, sophomore, Total. The second column is labeled M with entries 78, 38, 116. The third column is labeled S with entries 32, 65, 97. The fourth column is labeled E with entries 59, 42, 101. The fifth column is labeled H with entries 43, 51, 94. The sixth column is labeled Total with entries 212, 196, 408.
