Statistics and Probability Multiple Choice Questions.

Published on Aug 18, 2025 • Education

Introduction

Welcome to this tutorial on Statistics and Probability past questions. In this guide, we’ll go through some of the most commonly asked multiple-choice questions (MCQs), breaking them down step by step for better understanding. These are especially useful for students preparing for JUPEB, WAEC, NECO, NABTEB, and JAMB Mathematics exams.

Let’s get started with the questions and answers.

Question 1 – The Middle Value in a Set of Data

Question:
The middle value in a set of data arranged in order is called:

• A. Median
• B. Mean
• C. Mode
• D. Range

Explanation:
When data is arranged in ascending or descending order, the middle value is known as the median.

Correct Answer: A. Median

Question 2 – Chart Best for Showing Parts of a Whole

Question:
Which chart is best for showing parts of a whole?

• A. Histogram
• B. Bar Chart
• C. Pie Chart
• D. Frequency Polygon

Explanation:

• A histogram uses columns joined together to show frequency distribution.
• A bar chart uses separated bars to compare categories.
• A frequency polygon is a line graph derived from a histogram.
• A pie chart is a circle divided into sectors and is the best chart for representing parts of a whole.

Correct Answer: C. Pie Chart

Question 3 – Probability of Zero

Question:
If the probability of an event is zero, what does it mean?

• A. It is certain to happen
• B. Impossible to happen
• C. Likely to happen
• D. Equally likely to happen

Explanation:

• In probability, if P(E)= 1, the event is certain to happen.
• If P(E)=0, the event is impossible and will not happen.

Correct Answer: B. Impossible to happen

Correct Answer: 1/3

Conclusion – Mastering Statistics and Probability for Exam Success

Statistics and Probability are vital areas in JUPEB, WAEC, NECO, NABTEB, and JAMB mathematics exams. Mastering concepts like mean, median, mode, range, pie charts, histograms, and probability rules gives you a strong foundation to tackle both multiple-choice and theory questions.

From our solved examples, we learned that:

• The median is the middle value in ordered data.
• The pie chart is best for showing parts of a whole.
• A probability of zero means an event is impossible.
• The probability of rolling a number greater than 4 on a die is 13\tfrac{1}{3}31​.

By consistently practicing past questions and understanding the step-by-step solutions, you will gain confidence, improve your speed, and reduce mistakes in the exam hall. With focus and practice, success in Statistics and Probability is guaranteed.
