In this video, we’ll go step by step through cumulative frequency, the “less than” and “more than” methods, and how to plot both types of ogives clearly. With easy visuals and simple explanations, you’ll see not just how to draw them, but also why they work. By the end, you’ll be confident in interpreting data through ogives and ready to apply the concept in real-world problems and exams. Courses on Khan Academy are always 100% free.
