Activities cover reading and plotting scatter graphs, describing correlations, and drawing lines of best fit to estimate values from given contexts. Learners analyze pie charts to identify mode and grade proportions, justify comparisons using supporting evidence, and interpret cumulative frequency graphs to estimate median and minimum/maximum times. Further tasks include constructing box plots, drawing cumulative frequency curves from grouped tables, and calculating probabilities from two independent distributions.","Edexcel GCSE Maths-Interpreting Data (FH) [PhysicsAndMathsTutor.com](PhysicsAndMathsTutor.com)  \n1.
