Cumulative Frequency Diagram|Percentile & Median | IGCSE GCSE O Level Maths |Past Paper Oct/Nov 2015

In this video, we solve an important past paper question on Cumulative Frequency Diagrams from the Cambridge IGCSE Mathematics October/November 2015, Paper 0580, Question 24. The question involves interpreting a cumulative frequency curve for the distances travelled by 80 motorists in one month. We work step by step to find the median and the 30th percentile directly from the curve. 📊 Key Results from the Question: Median ≈ 1580 km 30th Percentile ≈ 1280 km By following this tutorial, you will learn: ✔ How to read data from a cumulative frequency curve. ✔ How to estimate the median using N/2 (here, 40th value). ✔ How to calculate a given percentile (here, 30% of 80 = 24th value). ✔ The importance of clear construction lines when projecting values from the graph. ✔ Common mistakes to avoid, such as confusing frequency with cumulative frequency or reading the wrong axis scale. Cumulative frequency is a vital part of the IGCSE/GCSE/O Level syllabus, as it helps us interpret data distribution and calculate percentiles and other measures of spread. Practising such past paper questions builds confidence and exam readiness. This lesson is especially useful for: IGCSE Mathematics (0580) students. GCSE Mathematics learners preparing for statistics questions. O Level Mathematics (4024) candidates revising cumulative frequency problems. By the end of this video, you will be confident in: Interpreting cumulative frequency curves. igcse maths cumulative frequency, igcse 0580 cumulative frequency, october november 2015 igcse maths, igcse maths past paper solution, igcse maths statistics past paper, igcse maths cumulative frequency diagram, igcse cumulative frequency curve, igcse cumulative frequency graph, igcse statistics cumulative frequency, igcse maths percentile question, igcse maths interquartile range, igcse maths median question, igcse median from graph, igcse maths statistics tutorial, igcse percentile explained, igcse percentile from graph, igcse maths cumulative curve solution, igcse cumulative frequency explained, igcse statistics percentile question, igcse cumulative frequency past paper, igcse maths percentile worked example, igcse statistics interquartile range, igcse 2015 maths past paper, igcse oct nov 2015 question 24, igcse 0580 question 24 solution, igcse past paper video solution, igcse cumulative graph question, igcse 2015 maths statistics solution, igcse worked example cumulative frequency, igcse graph statistics question, igcse 0580 cumulative graph tutorial, igcse cumulative frequency worked solution, igcse past paper explained, igcse statistics percentile tutorial, igcse cumulative graph method, igcse cumulative frequency curve explained, igcse cumulative frequency curve tutorial, igcse exam statistics question, igcse statistics revision video, igcse 0580 statistics past paper, igcse maths explained cumulative frequency, igcse cumulative graph median, igcse cumulative graph 30th percentile, igcse percentile from cumulative frequency, igcse statistics video lesson, igcse graph question solution, igcse past paper graph tutorial, igcse maths exam preparation statistics, igcse percentile and quartiles, igcse cumulative frequency revision, gcse maths cumulative frequency, gcse cumulative frequency curve, gcse cumulative frequency diagram, gcse cumulative frequency graph, gcse statistics percentile, gcse statistics cumulative frequency, gcse cumulative frequency tutorial, gcse median cumulative frequency, gcse 30th percentile cumulative frequency, gcse cumulative graph explained, gcse percentile from graph, gcse statistics revision video, gcse cumulative frequency exam tips, gcse cumulative frequency worksheet solution, gcse cumulative graph worked example, gcse exam cumulative frequency solution, gcse statistics interquartile range, gcse statistics median, gcse percentile calculation from graph, gcse graph question worked solution, o level maths cumulative frequency, o level cumulative frequency curve, o level cumulative frequency diagram, o level cumulative frequency graph, o level statistics cumulative frequency, o level percentile from cumulative frequency, o level median from graph, o level maths statistics past paper, o level cumulative graph tutorial, o level maths percentile explained, o level statistics revision, o level quartiles cumulative frequency, o level IQR from cumulative frequency, o level cumulative frequency question solved, o level maths past paper statistics, o level exam question cumulative frequency, o level cumulative graph worked solution, o level statistics question tutorial, o level cumulative graph exam tips, o level cumulative frequency practice, #IGCSE #GCSE #OLevel #CumulativeFrequency #MathsByZahfran
