Liam works at a zoo. He was looking at some data showing the masses of their 555 African elephants. The mean mass of the elephants was 3{,}800\,{\text{kg}}3,800kg3, comma, 800, start text, k, g, end text (kilograms), and the median mass was 3{,}600\,{\text{kg}}3,600kg3, comma, 600, start text, k, g, end text. The heaviest elephant, named Omar, was recorded as 6{,}000\,{\text{kg}}6,000kg6, comma, 000, start text, k, g, end text.
Liam then found out that Omar's mass was written down incorrectly, and that Omar actually has a mass of 7{,}000\,{\text{kg}}7,000kg7, comma, 000, start text, k, g, end text.
How will increasing Omar's mass affect the mean and median?
