Cumulative frequency Cumulative Frequency Graphs & Box Plots 1) The cumulative frequency graph below shows the results of a Year 8 science test. Josh got the highest mark in the class with 76. Samantha got the lowest with 7. A) Find the Median, Upper Quartile and Lower Quartile from the graph. B) Combine all this data to create a box plot. 3) These two tables show the results for Year 7 and Year 10 end-of-year English tests. Year 7 Min = 8 Max = 99 40 30 Upper Quartile Lower Quartile 0 0 10 20 F. C. F. 0�m� 20 21�m� 40 41�m� 60 61�m� 80 81�m� 100 15 22 18 11 4 15 37 55 66 70 A) Year Plot both sets.
