How to Draw Cumulative Frequency Curve (Ogive) | WAEC & NECO Exam Tutorials and Mathematics Guide

Описание: If you're preparing students for WAEC, NECO, or SSCE, this powerful Mathematics tutorial on Cumulative Frequency Curve (Ogive) is exactly what they need to master graph questions with confidence. In this step-by-step lesson, we break down how to construct a cumulative frequency table, calculate class boundaries, plot the ogive correctly, and use the graph to determine the median, interquartile range (IQR), and percentiles. Designed specifically for SSS students and candidates preparing for external examinations, this video simplifies what many students find difficult and turns it into an easy scoring opportunity.

Whether you're aiming for distinction in Mathematics or strengthening your statistics foundation, this tutorial provides clear explanations, exam-focused strategies, and practical worked examples using real SSCE-style questions. Learn how to choose the right scale, plot accurate points, interpret the S-shaped curve, and avoid common mistakes that cost students marks in exams. Watch till the end and transform cumulative frequency questions from confusion to confidence — because excellence in Mathematics starts with understanding the fundamentals.
