Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Calculate the midpoint of the class interval 10-20.
[1 mark]2.
Calculate the midpoint of the class interval 25-35.
[1 mark]3.
Calculate the midpoint of the class interval 40-50.
[1 mark]4.
Plot the midpoint of 10-20 on the graph paper.
[2 marks]B
Fluency & Practice
Complete the following to practice plotting midpoints.
1.
Find the midpoints for class intervals: 0-10, 20-30, 30-40.
[3 marks]2.
Plot midpoints 5, 25, and 35 on the grid.
[3 marks]C
Problem Solving & Reasoning
Answer the questions with full explanations.
1.
A class interval of 15-25 has a frequency of 12. What is the midpoint? How is this midpoint used in plotting the frequency polygon?
[4 marks]2.
Explain why midpoints are important when constructing frequency polygons.
[3 marks]D
Real-world Applications
Solve the word problems using your understanding of midpoints.
1.
A survey recorded the ages of children in a class: 5-10, 10-15, 15-20, 20-25. The frequencies are 4, 8, 6, and 2 respectively. Calculate the midpoints and describe how these points would be used to draw a frequency polygon.
[5 marks]E
Challenge & Extension
Tackle these more difficult problems to extend your understanding.
1.
Given class intervals 10-20, 20-30, 30-40 with frequencies 5, 15, and 10, calculate midpoints and explain how errors in midpoint calculation could affect the frequency polygon.
[4 marks]F
Mixed Review
Answer these questions to review your understanding of plotting midpoints.
1.
Plot midpoints 10, 20, 30, and 40 on the grid. Connect the points to form a frequency polygon.
[2 marks]2.
Identify and correct the mistake: A student calculated the midpoint of 5-15 as 12 instead of 10.
