Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Plot the points for the following data: (Hours of Study, Test Score): (2, 50), (4, 70), (6, 80).
[3 marks]2.
Using the plotted points, describe the overall trend between hours studied and test scores.
[2 marks]3.
Calculate the average test score for students who studied at least 4 hours.
[3 marks]4.
Identify if there is a positive, negative, or no correlation between hours studied and test scores in the data: (1, 45), (3, 55), (5, 65).
[2 marks]5.
A researcher records hours of study and number of pages read. The data points are: (3, 20), (5, 35), (7, 50). Plot these points on the grid.
[3 marks]6.
What is the nature of the relationship between hours studied and pages read based on the plotted data?
[2 marks]7.
A car's speed (km/h) and fuel consumption (litres/100km) are recorded. The data points are: (60, 8), (80, 10), (100, 12). Plot these points and comment on the relationship.
[4 marks]8.
Construct a scatter graph to show the relationship between age and number of hours spent on social media per week. Use the data points: (12, 10), (14, 15), (16, 20), (18, 25).
[4 marks]9.
Describe the trend shown by the scatter plot in question 8.
[2 marks]10.
Identify a possible outlier in the data: (10, 12), (12, 15), (14, 20), (16, 22), (25, 35). Explain your reasoning.
[3 marks]11.
A student incorrectly plots the points: (2, 30), (4, 50), (6, 70) but mislabels the axes. What common mistake might they have made?
