Count the number of non - zero values in the data set 2, 3, 6, 4, 7, 0, 4, 5, 0, 1, 2, 3, 2, 1, 4. The non - zero values are 2, 3, 6, 4, 7, 4, 5, 1, 2, 3, 2, 1, 4. There are 13 non - zero values.

Step2: Determine the ratio

The total number of surveyed students is 15. The ratio of the number of students who attended soccer games (non - zero values) to the total number of surveyed students is $\frac{13}{15}$.
