How we worked it out
Updated as you change the numbers.
- Sorted: 11, 12, 13, 14, 15, 15, 15, 17, 18, 20.
- Mean = sum ÷ count = 150 ÷ 10.
- Median = the middle value (average of the two middle values).
- Mode = the most frequent value(s).
Method and assumptions
The mean adds the values and divides by how many there are. The median is the middle value when sorted, which is less affected by extreme values. The mode is the most frequent value; a list can have several or none. The range is the largest minus the smallest.
