Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Calculate the approximate slope of the line passing through the points (2, 8) and (6, 2).
[2 marks]2.
Plot the graph of y = -3x for x values from 0 to 4. Draw the points on the grid.
[3 marks]3.
A scatter graph shows the relationship between hours studied and errors made in a test. The trend is clearly negative. Explain what this indicates about the relationship between these two variables.
[3 marks]4.
Given the data points (-1, 4), (0, 2), (1, 0), (2, -2), (3, -4), describe the overall trend and what it suggests about the relationship.
[2 marks]5.
Construct a scatter graph with the following data: (1, -2), (2, -4), (3, -6), (4, -8). What kind of correlation does this graph show?
[3 marks]6.
A student notices that when the temperature drops, the ice cream sales decrease. Is this an example of negative correlation? Explain briefly.
[3 marks]7.
Plot the points (-3, 9), (-2, 4), (-1, 1), (0, 0), (1, -1). Describe the trend.
[3 marks]8.
A line of best fit for a scatter plot shows a downward slope. What does this tell you about the correlation?
[2 marks]9.
Identify the error in this statement: 'A negative correlation means that as one variable increases, the other also increases.'
[2 marks]10.
Estimate the correlation of the data points: (1, 5), (2, 3), (3, 1), (4, -1), (5, -3).
[3 marks]11.
For the points (-2, 4), (0, 0), (2, -4), what is the approximate rate of change between the first and last points?
