GCSE 1 GCSE Edexcel Higher: November 2017 Paper 3, Q 11 The cumulative frequency graph shows information about the weights of 60 plants. 1 Edexcel Higher: November 2017 Paper 3, Q 11 The cumulative frequency graph shows information about the weights of 60 plants. 60 60 50 50 40 40 Cumulative frequency 30 20 20 10 10 0 20 30 40 50 60 Weight (g) 0 70 (a) Use the graph to find an estimate for the median weight. Mark says, “ 70 – 30 = 40 so the range of the weights is 40 g” (b) Is Mark correct? You must give a reason for your answer. 30 40 50 60 Weight (g) 70 (a) Use the graph to find an estimate for the median weight. (1) 20 Mark says, “ 70 – 30 = 40 so the range of the weights is 40 g” (b) Is Mark correct? You must give a reason for your answer.
