Mode
The mode is the number that appears most frequently.
In this set of numbers, 7, 8, and 9 each appear twice. Therefore this data set has multiple modes, which are 7, 8 and 9.
Mean
To find the mean, we add all numbers together and then divide by how many numbers there are.
The sum of the numbers is 197, and there are 14 numbers, so the mean is:
Median
To find the median, we first need to order the numbers from least to greatest, then find the middle number.
If there is an even number of numbers, the median is the mean of the two middle numbers.
In this set, the ordered list is:
- 4, 5, 6, 7, 7, 8, 8, 9, 9, 10, 11, 12, 13, 88
The two middle numbers are 8 and 9, and their mean is 8.5, so the median is 8.5.
