Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Given the cumulative frequency data: 0, 5, 12, 20, 28, 35. Plot the cumulative frequency curve on the grid provided.
[3 marks]2.
Using the plotted graph, estimate the cumulative frequency for the value corresponding to 6 on the x-axis.
[2 marks]3.
Calculate the median value from the cumulative frequency data: 0, 5, 12, 20, 28, 35.
[3 marks]4.
Construct a cumulative frequency graph for the data points: (x=1, CF=2), (x=3, CF=5), (x=5, CF=9), (x=7, CF=14). Use the grid to draw the plot.
[4 marks]5.
Describe the shape of the cumulative frequency curve you plotted. Is it linear, concave, or convex? Explain briefly.
[2 marks]6.
A student plots a cumulative frequency graph but accidentally flips the axes. Identify the mistake and explain the correct approach.
[3 marks]7.
Plot the cumulative frequency curve for the following data: 0, 3, 7, 15, 22, 30. Use the grid.
[4 marks]8.
Estimate the total number of data points from your plotted graph.
[2 marks]9.
A graph shows a cumulative frequency of 0 at x=0 and 40 at x=8. If the data points are evenly spaced, what is the approximate cumulative frequency at x=4?
[2 marks]10.
Identify a common mistake when plotting cumulative frequency graphs and explain how to avoid it.
[3 marks]11.
Challenge: Given a set of cumulative frequency data, determine the quartile values by plotting and interpreting the graph. Data: 0, 8, 15, 22, 30.
