Liam works at a zoo. He was looking at some data showing the masses of their 5 African elephants. The mean mass of the elephants was 3,800 kilograms and the median mass was 3,600 kilograms. The heaviest elephant, named Omar, was recorded as 6,000 kilograms. Liam then found out that Omar's mass was written down incorrectly, and that Omar actually has a mass of 7,000 kilograms. How will increasing Omar's mass affect the mean and median?

Respuesta :

By increasing Omar's mass, the mean(average) will rise, because the number of elephants stays the same, but the weight of the elephants added up increases. Although, the median is just the elephant in the middle of the data set, so the median will stay the same.
