Grouped Frequency Distribution

Normally, the data which we received is unorganized. Such data's which are unorganized are known as Raw Data.

Example - In a class of 20 students. Students were asked for their favorite game. And their answers are as follows:
Football, cricket, volley ball, badminton, volley ball, cricket, football, cricket, volley ball, football, badminton, football, cricket, volley ball, football, cricket, badminton, football, cricket, volley ball.

You can observe that the above answers of 20 students represent an unorganized and raw data.

Now, it's very difficult to know which is most like game and which is the least liked. And for this we first need to organize this raw data

So, answer of 20 students is now rearranged and organized in the following way:

Favorite Game Liked by Number of Students
Football 6
Cricket 6
Volley ball 5
Badminton 3
Total 20

Above table is organized formed of data. From this table we can easily find that 20 students told about their favorite game.

We can also find that football and cricket is most liked among all students and badminton is the least like game.

Column two of the above table Liked by Number of Students represents the frequency. Frequency represents that a particular subject matter or entry occurred how many times. And the above table which is the organized form of raw data is known as Frequency Distribution Table
