Data Handling

Class 2

🎯 Learning Objectives

📖 Let Us Begin!

Meena's teacher asked the class: "What is your favourite fruit?" Some children said mango, some said banana, and some said apple. The teacher wrote down all the answers. This collection of information is called data. We can show data using tally marks and pictures to make it easy to read.

Tally Marks

Tally marks are a quick way to count. We draw lines to count. Every 5th mark crosses the previous 4 marks.

How to draw tally marks:
1 = |    2 = ||    3 = |||    4 = ||||    5 = |||| (with a cross line)
6 = |||| |    7 = |||| ||    8 = |||| |||
Example: Ravi counted the birds in his garden. He saw 7 sparrows, 4 crows, and 3 pigeons.
Sparrows: |||| || (7)    Crows: |||| (4)    Pigeons: ||| (3)

Pictograph

A pictograph uses pictures or symbols to show data. Each picture stands for a certain number.

Example Pictograph: Favourite Fruits in Class 2
(Each picture = 1 child)
FruitNumber of children (each * = 1 child)
Mango* * * * * (5)
Banana* * * (3)
Apple* * * * (4)
Orange* * (2)
From this pictograph: Mango is the most popular fruit. Orange is the least popular. Total children = 5 + 3 + 4 + 2 = 14.
