Checklist ROAI 2025 County Stage · Task 1
Calorie Consumption
Romanian title: Consum Caloric
Compute four statistics of an activity dataset and predict calories burned, including for a subset representing a men's handball team.
The task
Each record describes a physical activity by user ID, gender, age, height, weight, duration, average heart rate and average body temperature; the training set also gives the calories burned.
Part 1 asks for the number of training rows, the number of rows for men, the mean activity duration and the number of users aged 75 or over. Part 2 asks for predicted calories for test rows with Subtask = 5 and for test rows with Subtask = 6 (a men's handball team).
Abridged and translated by SOTA from the official Romanian materials. The official statement has the exact rules, and it wins wherever this summary differs.
