Finding the mode of a data set involves finding the data values that appear most often in the set. You need all the values of the data in the set.
- Determine the data values
Determine the value of each datum in the set. They should be in the same units.
- Arrange the data values
Arrange the data values in ascending order.
- Determine the frequency of each datum value
Find out how many times each datum value appears in the set.
- Find the mode
Find the data values that appear most often in the set. This is the mode. For example, in the data set 2, 4, 7, 7, 8, 9, the mode is 7, since it appears most often.
