Step 1: Identify the column heads

The column heads in the table represent the variables being measured for each student. These are: Male, Age, Eye Color, Shoe Size, Height (inches), Weight (pounds), Number of Siblings, College Units This Term, and Handedness.

Step 2: Count the number of variables

Count the number of column heads listed in Step 1. There are 9 distinct column heads.
