How do you calculate mean and median?
Mean vs Median
- The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.
- The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
