To determine which column shows the individuals in the study, we need to identify the column that lists the names of the students, as the individuals are the specific people involved in the study.
Let's examine each column:
1. Student: This column lists the names of the individuals (Darla, Emilio, Grace, Talia, Rodney, and Evan).
2. Grade: This column lists the grades of the students (10, 12, 12, 10, 11, 12).
3. Instrument: This column lists the instruments the students play (trombone, saxophone, trumpet, saxophone, trumpet, saxophone).
4. Class Period: This column lists the class periods of the students (4, 2, 4, 1, 2, 2).
Since the question asks for the column that shows the individuals in the study, and the "Student" column is the one that lists the names of the students, we can conclude that the correct answer is:
Student
