Data handling

Data in Table for Class 1 Math

This discussion is to inform the students about the data handling and how to arrange data tables. Arranging data in table is the simplest way to represent data easily. From this concept the students will get to know about data and data table.

Also, the student will learn to

  • Summarise and compare data in a planned way
  • Express data using appropriate picture to make a pictograph

Each concept is explained to class 1 maths students with examples and illustrations, and a concept map is given at the end to summarise the idea. At the end of the page, two printable Pictograph worksheets with solutions are attached for students to practice. Download the worksheets and assess your knowledge.

What Is Data Handling?

We have learned about Picture graphs. Now let’s learn about handling data using the table.

What is the difference between pictograph and table?

  • Pictograph is the representation of the data in the form of pictures or symbols.
  • We can arrange data using a table.

Data Table

  • To create a table, we have to first collect the data, organize it properly, and then represent it in the form of a table.
  • A table consists of rows and columns.

Examples:

   Table format looks like this:

Rows run horizontally and columns run vertically down. When rows and columns are put together, they make a table.

Table image
  • Each box of a table is called a cell.
  • Example:

    Cell image
  • In the first-row, first column cell, label the objects that you want to represent in the table. And the first cell of the second column is used to indicate the number of objects or numeric values in the data.
  • Example:

    Example table image

Why table is a good way to represent the data?

Let’s see an example.

Examples:

   Rahul’s mom asked him to bring some fruits from the market.
Student Image

To remember the number of fruits, Rahul makes a list using table.

He made a table like this:

Fruit table image
  • In the first column, he mentioned the names of the fruits and in the second column, he mentioned the number of that fruit.
  • From the table, Rahul can easily remember the number of the fruits and bring the correct number of fruits from the market.

A table helps us to interpret the data easily.

How to make a table from a pictograph?

Examples:

   Here in the pictograph, the information about the number of students absent in a class is given.

Now, from this pictograph make a table.

  • Step 1: Decide the labels of the columns.In the first column of the pictograph, days are mentioned. So, in the table first column will be labelled as ‘Days’. In the second column of the pictograph, symbols for the number of children are given. So, the second column of the table will labelled as ‘Number of students absent’.
  • The table will look like this:

    Weekdays table image
  • Step 2: By using the given key, find out the numeric data.The given key indicates that one symbol represents 2 children. Monday = 4 symbols (Add the number 2 four times) = 2 + 2 + 2 + 2 = 8 children Tuesday = 1 symbol = 2 children Wednesday = 3 symbols (Add the number 2 three times) = 2 + 2 + 2 = 6 children Thursday = 2 symbols (Add the number 2 two times) = 2 + 2 = 4 children Friday = 2 symbols (Add the number 2 two times) = 2 + 2 = 4 children
  • Step 3: By using this numeric data complete the table.By putting these numbers in the table, it will look like:
  • Table for children

So, from the pictograph, we can make a table.
