Here we will learn how to use of tally marks.

When the

observations are large, it may not be easy to find the frequencies by simply

counting, so we make the use of bass (|, \) called the tally marks.

Tallies are

usually marked in bunches of five.

The first

four tallies are marked vertically. The fifth tally in a bunch is marked diagonally

across the earlier 4.

**The
illustration of the example will help us to learn the use of tally marks:**

The scores

obtained in 20 throws of a dice are:

5, 4, 3, 2,

1, 1, 2, 5, 4, 6, 6, 6, 3, 2, 1, 4, 3, 2, 2, 4

Prepare the

frequency table for the above scores.

**Solution:**

Frequency table of scores in 20 throws.

**Here;**

1 occurs 3 times

2 occurs 5 times

3 occurs 3 times

4 occurs 4 times

5 occurs 2 times

6 occurs 3 times
