Data

📊 What Is Data?

Data is information we collect and organize so we can learn something.

We can collect data by:

• Asking questions (like a survey)
  
  

• Counting objects
  
  

• Observing what we see
  
  

Then we show our data using charts and graphs.

✍️ How to Collect Data

We can collect data by asking a question. For example:

“What is your favorite fruit?”

Then we count the answers.

Fruit

Number of Students

Apple

4

Banana

3

Orange

2

✅ This is called a data table.

✅ What Are Tallies?

Tallies are short lines we draw to count quickly.
We draw four straight lines, then a line across for five (like this: |||| and then ||||\).
