Understand the idea
For an odd number of observations, the median is the middle sorted value. A large outlier can affect the mean more than the median.
WORKED EXAMPLE
Sorted times 3, 4, 5, 6, 22 have median 5. Their mean is 8. The large value matters when describing the typical session.

Exercises with feedback
MAKE SOMETHING YOU CAN EXPLAIN
Your practical challenge
Calculate mean and median, then explain which you would report for a stated purpose. Keep the outlier visible.
These ticks are your self-review. They do not automatically assess project quality. Ask an adult or partner to review what you can show.
Use the skill in a new situation
Explain why deleting an unusual result needs evidence, not convenience.
