How to Calculate the Median. The median is the middle score of a distribution. Consider this set of numbers: 5, 7, 9, 9, 11. Since you have an odd number of scores, the median would be 9. Now, what happens when you have an even number of scores so there is no single middle score. Consider this set of numbers: 1, 2, 2, 4, 5, 7. Since there are an even number of scores, you need to take the average of the middle two scores.
The platypus (Ornithorhynchus anatinus) also known as the duck-billed platypus is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania.
The platypus is one of the most unusual creatures in the animal kingdom. Platypuses (which is the correct plural form, not platypi) have a paddle-shaped tail like a beaver; a sleek, furry body like an otter; and a flat bill and webbed feet like a duck.In fact, the first time a platypus was brought from Australia to Britain, people couldn't believe that it was a real animal.latypuses (which is the correct plural form, not platypi) have a paddle-shaped tail like a beaver; a sleek, furry body like an otter; and a flat bill and webbed feet like a duck.
