Question 6
3 marks · Easy
Answer and see the solution →The histograms show the test scores of two different classes in a maths test.
Histogram for Class X Histogram for Class Y (a)[1 mark]Which class had more students scoring between 40% and 70%?
(b)[1 mark]Which class has the largest number of students with low scores (0–40%)?
(c)[1 mark]Which class has the most even spread of scores? Give a reason for your answer.
Question 7
2 marks · Easy
Answer and see the solution →Two histograms represent the test marks for two different science groups, P and Q. The modal class for Group P is 30–50 marks and for Group Q is 70–90 marks.
Which group performed better overall? Write the modal class of the better performing group and explain why it shows better overall performance.
