Using Percent to Compare Data

The video tutorial explains how to solve a math test question using percentages to compare data. It involves analyzing a table that shows the number of students participating in sports across different age groups. The tutorial guides viewers through calculating the percentage of students participating in sports for two age groups, 7-10 and 15-18, and finding the difference between these percentages. The result shows that 33% more students in the younger age group participate in sports compared to the older age group.
