Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Given the cumulative frequency data: 10, 25, 40, 55, 70 for class intervals, plot the cumulative frequency graph on the grid.
[3 marks]2.
Using the plotted graph, estimate the median class and value.
[3 marks]3.
Construct a cumulative frequency graph for the following data: 15, 30, 45, 60, 75, 90.
[3 marks]4.
Describe how to find the mode from a cumulative frequency graph.
[2 marks]5.
Plot the cumulative frequency curve for the data: 5, 15, 25, 35, 50, 65.
[3 marks]6.
A dataset's cumulative frequency graph shows a sudden jump from 20 to 40 at a certain point. What does this indicate about the data?
[2 marks]7.
Given the following cumulative frequency data: 8, 16, 24, 32, 40, plot the graph and find the approximate interquartile range (IQR).
[4 marks]8.
Identify and correct the error in a cumulative frequency graph that shows a decreasing trend.
[3 marks]9.
A survey reports the following class intervals and cumulative frequencies: 10, 30, 50, 70. Plot the data and explain what the shape of the graph indicates about the distribution.
[4 marks]10.
Challenge: Given two cumulative frequency curves, determine which dataset has a higher median and justify your answer.
