How to use the Frequency table to organize data?

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.

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.
