What is Data?

A school conducts a lot of events for the holistic development of the students. Physical activity,
including participation in sports, has been linked to improved cognitive function, attention, and
concentration. Students who are physically active may experience better focus in the classroom,
leading to enhanced academic performance.

In the Annual Sports Day, class VI students from different sections are nominated for different
sports, as shown in the table below.
