Definition

What is it?

A data question is a question that can be answered by collecting and looking at information, or 'data'. It's a question that needs facts and numbers, not just opinions, to find an answer.

Simple Example

Quick Example

Imagine you want to know which flavour of ice cream is most popular in your school canteen. This is a data question because you can collect information (data) by asking students their favourite flavour and then counting the votes to find the most popular one.

Worked Example

Step-by-Step

Let's say your teacher wants to know if more students prefer to read storybooks or comics during free time.

1. First, we need to ask each student in the class whether they prefer storybooks or comics.
2. Let's say 15 students say 'storybooks' and 10 students say 'comics'.
3. We collect this information (data).
4. Now, we can compare the numbers: 15 is greater than 10.
5. So, the answer to the data question 'Do more students prefer storybooks or comics?' is: More students prefer storybooks.

Answer: More students prefer storybooks.

Why It Matters

Understanding data questions helps you make smart decisions in everyday life and in big careers. Scientists use them to understand the world, economists use them to study money, and even cricket analysts use them to improve team strategies. It's a key skill for jobs in technology, finance, and research.

Common Mistakes

MISTAKE: Asking a question that can only be answered by opinion (e.g., 'Is mango the best fruit?'). | CORRECTION: Make sure your question can be answered with facts and numbers that can be collected.

MISTAKE: Asking a question that is too general or vague (e.g., 'What do people like?'). | CORRECTION: Make your question specific enough to collect clear data (e.g., 'What fruit do students in Class 6 prefer?').

MISTAKE: Asking a question that doesn't have a clear way to collect data (e.g., 'Are all clouds happy?'). | CORRECTION: A good data question should suggest how you might collect the information needed to answer it.

Practice Questions

Try It Yourself

QUESTION: Is 'What is your favourite colour?' a data question? | ANSWER: Yes, because you can ask people and count their answers.

QUESTION: Your friend asks, 'Which mobile phone brand is the best?' Is this a good data question? Why or why not? | ANSWER: No, it's not a good data question because 'best' is an opinion. A better data question might be 'Which mobile phone brand do most students in Class 7 use?'

QUESTION: Your school principal wants to know if students prefer having an extra sports period or an extra art period each week. Formulate this into a clear data question and suggest how you would collect the data. | ANSWER: Data Question: 'Do students in our school prefer an extra sports period or an extra art period each week?' To collect data, you could conduct a survey where each student votes for 'Sports' or 'Art'.

Real World Connection

In the Real World

When a company like Swiggy or Zomato wants to know which areas have the most food orders, they ask a data question like 'Which pincodes have the highest number of lunch orders between 1 PM and 2 PM?' They then collect data from their app to find the answer, which helps them decide where to focus their delivery services.
