In a survey, people usually collect lots of data, also known as raw data. Raw data can be arranged in a frequency table.
A frequency table shows the number of times each value occurs. The mode is the data with the highest frequency.
Example:
The following data shows the test marks obtained by a group of students.
Draw a frequency table for the data and find the mode.
| 6 | 7 | 7 | 1 | 3 | 2 | 8 | 6 | 8 | 2 |
| 4 | 4 | 9 | 10 | 2 | 6 | 3 | 1 | 6 | 6 |
| 9 | 8 | 7 | 5 | 7 | 10 | 8 | 1 | 5 | 8 |
Solution:
Go through the data; make a stroke in the tally column for each occurrence of the data. The number
of strokes will be the frequency of the data.
The mode is 6 and 8 since they both have the highest frequency of 5.
