Class 6 AI: Basic Data Concepts – Questions and Answers

The Basic Data Concepts chapter teaches that data is recorded facts and observations, and that AI is only as good as the data it learns from. Students sort data into types, spot missing or wrong entries, and learn which personal data to protect.

[ WORKED EXAMPLE ]

Which of these is data?

Answer: Daily temperatures recorded for a month.

  1. Data means recorded facts or observations.
  2. Temperatures noted each day are recorded observations.
  3. The other options are not recorded facts.

What this chapter is about

Students learn what data is, the difference between structured data (tables) and unstructured data (photos, audio, free text), and between numbers and categories.

They practise checking data quality: is it complete, correct and representative of the group we care about?

They also learn that some data is personal and sensitive, and should not be shared.

[ HANDS-ON ACTIVITY ]

Sort it: structured or unstructured data?

Structured data fits neatly into rows and columns. Unstructured data does not.

      Q1Which of these is data?
      • Daily temperatures recorded for a month
      • A wish to be taller
      • The colour of tomorrow’s sky
      • A dream you forgot

      Answer: A. Daily temperatures recorded for a month

      Hint: Data is something recorded or observed.

      1. Data means recorded facts or observations.
      2. Temperatures noted each day are recorded observations.
      3. The other options are not recorded facts.

      Q2A table with student names in one column and marks in another is…
      • Structured data
      • Unstructured data
      • Not data at all
      • A computer program

      Answer: A. Structured data

      Hint: Is it organised into rows and columns?

      1. Structured data is organised in a fixed format such as a table.
      2. Photos, voice notes and free text are unstructured.
      3. A names-and-marks table is structured data.

      Q3In a survey, “favourite colour” is which kind of data?
      • Categorical (labels or groups)
      • Numerical (measurements)
      • A password
      • Image data

      Answer: A. Categorical (labels or groups)

      Hint: Can you do arithmetic with colours?

      1. Numerical data is counted or measured, like height or marks.
      2. Colours are labels that sort answers into groups.
      3. So favourite colour is categorical data.

      Q4A survey of only Class 6A students is used to claim what the whole school likes. What is the problem?
      • The data does not represent the whole school
      • The survey had too many questions
      • Class 6A students are always wrong
      • Surveys can never be used

      Answer: A. The data does not represent the whole school

      Hint: Who is missing from the data?

      1. The claim is about every class in the school.
      2. Only one class was asked, so other classes’ views are missing.
      3. The data is not representative, so the claim is not reliable.

      Q5In a list of marks out of 100, one entry says 950. What should you do?
      • Check the entry and correct it, because it is likely an error
      • Keep it, because data is never wrong
      • Delete the whole list
      • Give everyone 950

      Answer: A. Check the entry and correct it, because it is likely an error

      Hint: Is 950 possible in a test marked out of 100?

      1. A mark cannot be more than 100, so 950 is impossible.
      2. It is probably a typing error (perhaps 95 or 50).
      3. Check the original record and correct it before using the data.

      Q6Which is personal data you should NOT post publicly?
      • Your home address and phone number
      • Your favourite cricket team
      • The name of your favourite book
      • Your opinion of a movie

      Answer: A. Your home address and phone number

      Hint: Which information could help a stranger find or contact you?

      1. An address and phone number can identify and locate you.
      2. Opinions and favourites are much lower risk.
      3. Keep your address and phone number private.

      Frequently asked questions

      What does the Class 6 Basic Data Concepts AI chapter cover?

      The Basic Data Concepts chapter teaches that data is recorded facts and observations, and that AI is only as good as the data it learns from. Students sort data into types, spot missing or wrong entries, and learn which personal data to protect.

      Which computational thinking skills does Basic Data Concepts use?

      Basic Data Concepts mainly practises abstraction, decomposition. It links to Part 2: Artificial Intelligence.

      Where are the official CBSE Basic Data Concepts questions?

      The official questions are in the CBSE Class 6 Computational Thinking and AI handbook for 2026-27, free on the CBSE Academic website. The practice on this page is original and mapped to the same chapter.
