Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Plot the points for the data: (2, 5), (4, 7), (6, 9), (8, 11).
[4 marks]2.
Calculate the correlation coefficient approximately for the dataset: (1, 2), (2, 4), (3, 6), (4, 8).
[3 marks]3.
Describe the relationship between the variables based on the plotted points.
[2 marks]4.
Construct a scatter graph to show the data: hours studied vs. test scores — (1, 50), (2, 55), (3, 65), (4, 70).
[4 marks]5.
Identify whether there is a positive, negative, or no correlation in the data: (5, 20), (10, 18), (15, 15), (20, 10).
