Watch all other items here:    • 2025 UCE Mathematics Paper Solutions – UNE...   Are you preparing for your UCE Mathematics 2025 Paper? In this video, we solve a data analysis question about learners’ performance before and after a new mathematics teacher was employed. You’ll learn how to: Find the mean score from a histogram (Graph 1). Calculate the percentage of learners below the pass mark (55%) using cumulative frequency and interpolation. Interpret the results to determine if performance improved or declined. This step-by-step explanation follows UNEB marking style — perfect for Senior Four students, teachers, and candidates revising for UCE examinations. 📚 Watch till the end to understand how to compare performance using statistical measures in mathematics.
