Class 8 Mathematics — Chapter 4: Data Handling
72 practice questions · 24 Easy · 24 Medium · 24 Hard
Practise Class 8 Mathematics Chapter 4, "Data Handling", with 72 NCERT-aligned multiple-choice questions. The set is split into 24 Easy, 24 Medium and 24 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams.
"Data Handling" is one of the chapters where problem-solving speed, formula recall and step-by-step reasoning really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Data Handling, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 8 Mathematics mastery score. A few sample questions are shown below; sign in free to practise all 72.
Key concepts: Data Handling (Class 8 Mathematics)
This chapter covers organising and representing data through grouped frequency tables, histograms and pie charts, and introduces basic probability.
- Organising data
- Raw data is grouped into class intervals with frequencies to make it easier to interpret.
- Histogram
- A bar graph for grouped continuous data with no gaps between bars; the bar height shows frequency.
- Pie chart
- A circle divided into sectors; each sector's angle is proportional to its share of the total (out of 360°).
- Probability
- The chance of an event = (number of favourable outcomes)/(total number of outcomes); lies between 0 and 1.
- Random experiment
- An experiment whose outcome cannot be predicted with certainty, e.g. tossing a coin or rolling a die.
Key formulas — Data Handling
💡 Exam tips for Data Handling
- For a pie chart, the sector angles must add up to 360° — check this to catch errors.
- Probability is always between 0 (impossible) and 1 (certain).
Sample questions
Pie chart represents data using:
Each sector ∝ frequency.
P(getting 5 on a die):
One favourable out of 6.
A pie chart of 540 students shows Maths 150°, Science 120° and English 90°; the rest chose Sports. How many students chose Sports?
Sports takes 360° − (150° + 120° + 90°) = 80°, and (80 ÷ 360) × 540 = 120 students.
