Think Tank Logical Thinking
A maths teacher of class V collects information about the colour each student likes.
Red, Pink, Blue, Red, Green, Black, Purple, Blue, Red, Black, Purple, Pink, Blue, Yellow, Red, Blue,
Purple, White, Pink, Yellow, Brown, Pink, Brown, Green, Red, Black, Blue, Purple, Black, Blue
Read the above information and answer the following questions.
1. How many students like red? 2. How many students like yellow?
3. Which is the least preferred colour? 4. Which is the most preferred colour?

Organising Data using tally marks

Example 2: The sizes of shoes worn by 32 students of class V are given below:

5 6 4 6 7 5 6 5
6 5 4 6 5 6 5 6
7 7 6 6 7 7 6 6
4 7 7 5 5 6 5 6

Organise the data in tabular form using tally marks.
Solution: Step 1: Look at the given data. In how many categories can the data be
grouped? Here, the shoe sizes are 4, 5, 6 and 7.
Step 2: Make a table with a suitable Shoe Tally Number of

number of columns and rows size marks students
(here, 3 columns and 6 rows) and 4 ||| 3
label them as shown alongside. 5 |||| 9
Step 3: Now, cross out one number at 6 ||| 13
a time and add a bar to the 7 || 7
corresponding row of tally marks. Total = 32
Continue adding the tally marks by
crossing out all the items (data).
Step 4: Now, write the number of students for each shoe size by counting the
bars in each respective row.

Step 5: Find the total number of students by adding the number of students
in all the rows.

We can easily find the number of students wearing a particular shoe size.

Teacher’s Encourage the children to arrange the given data in ascending order before grouping the data into categories.
