AQA GCSE · Question 05.2 · Social Context and Behaviour

Scatter graph of Confidence vs. Likelihood of Intervening Likelihood of saying something (1-5) 0 1 2 3 4 5 Confidence rating (1-5) 1 2 3 4 5

Participants were asked to rate their confidence levels on a scale from 1 (low) to 5 (high). They used a similar scale to rate how likely they are to say something when they see someone dropping litter. The results are shown in Table 1.

Use the results in Table 1 to sketch a suitable graph to show the ratings for participants' confidence and the likelihood of them saying something when witnessing littering.

Also include in your answer:

  • a label for the Y axis
  • a scale for both axes
  • a suitable title for your graph.

How to approach this question

1. Identify the two variables: 'Confidence rating' and 'Likelihood of saying something'. These will be your X and Y axes. 2. Choose the correct type of graph. Since you are looking for a relationship between two co-variables, a scatter graph is most appropriate. 3. Draw and label the axes. The X-axis should be 'Confidence rating' and the Y-axis should be 'Likelihood of saying something'. Both scales should run from at least 1 to 5. 4. Give the graph a clear, descriptive title, such as 'A scatter graph to show the relationship between confidence and likelihood of intervening'. 5. Carefully plot each pair of scores from the table as a single point on the graph. For example, participant A is (5, 4).

Full Answer

A correctly drawn scatter graph showing the relationship between confidence rating and the likelihood of saying something. The graph should have a suitable title, correctly labelled X and Y axes with scales, and all 10 data points plotted accurately.
A scatter graph is used to represent the relationship between two continuous variables. Each point on the graph represents one participant's scores on both variables. In this case, 'Confidence rating' is the independent variable (plotted on the x-axis) and 'Likelihood of saying something' is the dependent variable (plotted on the y-axis). By plotting the points, we can visually inspect the data for a pattern or correlation. In this case, the points generally go from the bottom-left to the top-right, suggesting a positive correlation: as confidence increases, the likelihood of saying something also tends to increase.

Common mistakes

Common mistakes include choosing the wrong type of graph (like a bar chart), forgetting to label one or both axes, not providing a title, or inaccurately plotting the data points.
